configs/releng/syslinux/archiso_pxe-linux.cfg: replace checksum and verify with cms_verify=y

Specify `cms_verify=y` in SYSLINUX/PXELINUX configuration to use OpenSSL
CMS based method for verifying the root file system image against the
code signing certificates in the initramfs.

`checksum` and `verify` are removed since they essentially serve the same
purpose and performing all the checks just needlessly delays boot.
Additionally, the removal of `verify` allows to build the ISO without gpg,
i.e. without using `mkarchiso`'s `-g` and `-G` options.

Fixes #200
