CI: avoid repacking initrd as part of the test job

Use the new test-artifacts which provide rootfs.cpio.gz rather than
initrd.tar.gz.  rootfs.cpio.gz also has all the necessary top-level
directories, and includes the rc_verbose setting, so these modifications can
be dropped.

Having that, do not repack the whole initrd, but only pack modified
files and rely on Linux handling of concatenated archives.
This allows packing just test-related files (which includes the whole
toolstack), instead of the whole initrd.

For xilinx-smoke-dom0-x86_64.sh, this involves instructing grub not to unzip
the archive, as doing so corrupts it.
