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".
