Fixes #174

Subject: mkarchiso: copy all GRUB files to the ISO

Do not limit file copying to only grub.cfg and instead copy all GRUB configuration files and assets to both the ISO9660 and FAT image.
This will allow for including custom images, fonts, etc.

To easily match all non-configuration files (i.e. files without the .cfg extension), bash's extended glob feature will be enabled.
Actions common to multiple _make_bootmode_uefi-*.grub are split off into dedicated functions:

* _make_common_bootmode_grub_copy_to_efibootimg,
* _make_common_bootmode_grub_copy_to_isofs,
* _make_common_bootmode_grub_cfg.

Use the same du command in all efiboot_imgsize variable assignments.

Fixes #185.

Subject: mkarchiso: preload more GRUB modules and disable shim_lock verifier

--disable-shim-lock is required to support Secure Boot with custom signatures without using shim.
Otherwise GRUB will trow an error when trying to boot a kernel:

    error: shim_lock protocol not found.
    error: you need to load the kernel first.

The modules GRUB will use need to be preloaded otherwise the EFI binaries cannot be signed and used for Secure Boot.
See https://bugs.archlinux.org/task/71382.
GRUB will trow en error:

    error: verification requested but nobody cares

These changes are done to support Secure Boot using custom keys (not shim) by simply extracting the boot loader
(BOOTx64.EFI and BOOTIA32.EFI), kernel, UEFI shell, signing them and then repacking the ISO.

For example.
Extract the files:

    $ osirrox -indev archlinux-YYYY.MM.DD-x86_64.iso \
        -extract_boot_images ./ \
        -extract /EFI/BOOT/BOOTx64.EFI BOOTx64.EFI \
        -extract /EFI/BOOT/BOOTIA32.EFI BOOTIA32.EFI \
        -extract /shellx64.efi shellx64.efi \
        -extract /shellia32.efi shellia32.efi \
        -extract /arch/boot/x86_64/vmlinuz-linux vmlinuz-linux

Make the files writable:

    $ chmod +w BOOTx64.EFI BOOTIA32.EFI shellx64.efi shellia32.efi vmlinuz-linux

Sign the files:

    $ sbsign --key db.key --cert db.crt --output BOOTx64.EFI BOOTx64.EFI
    $ sbsign --key db.key --cert db.crt --output BOOTIA32.EFI BOOTIA32.EFI
    $ sbsign --key db.key --cert db.crt --output shellx64.efi shellx64.efi
    $ sbsign --key db.key --cert db.crt --output shellia32.efi shellia32.efi
    $ sbsign --key db.key --cert db.crt --output vmlinuz-linux vmlinuz-linux

Copy the boot loader and UEFI shell to the EFI system partition image:

    $ mcopy -D oO -i eltorito_img2_uefi.img BOOTx64.EFI BOOTIA32.EFI ::/EFI/BOOT/
    $ mcopy -D oO -i eltorito_img2_uefi.img shellx64.efi shellia32.efi ::/

Repack the ISO using the modified El Torito UEFI boot image and add the signed boot loader files, UEFI shell and
kernel to ISO9660:

    $ xorriso -indev archlinux-YYYY.MM.DD-x86_64.iso \
        -outdev archlinux-YYYY.MM.DD-x86_64-Secure_Boot.iso \
        -boot_image any replay \
        -append_partition 2 0xef eltorito_img2_uefi.img \
        -map BOOTx64.EFI /EFI/BOOT/BOOTx64.EFI \
        -map BOOTIA32.EFI /EFI/BOOT/BOOTIA32.EFI \
        -map shellx64.efi /shellx64.efi \
        -map shellia32.efi /shellia32.efi \
        -map vmlinuz-linux /arch/boot/x86_64/vmlinuz-linux

Boot the resulting archlinux-YYYY.MM.DD-x86_64-Secure_Boot.iso.

Subject: Add the ability to generate rootfs signatures using openssl CMS
 module if ``-c`` is given.

(gitlab ci)

Added a CA structure to the codesigning certificates.
This to test the functionality of optional CA being in the signing message.

(mkarchiso)
Removed the ``sign_netboot_artifacts`` variable and instead
we'll now rely on ``if [[ -v cert_list ]]; then``.

Added ``ARCHISO_TLS_FD`` and ``ARCHISO_TLSCA_FD`` environment variables
to override the certificates used. This is so that third party CA's can
be used during building in a meaningful way without distrupting the
CA trust that is shipped by default.

_cms_sign_artifact() was added which signs the rootfs using OpenSSL CMS.
The files will be saved as "${artifact}.cms.sig". That would be for instance
"${isofs_dir}/${install_dir}/${arch}/airootfs.sfs.cms.sig".
