Test the boot image migration as omarchy-migrate runs it, and a failed rebuild

The test ran the migration with plain bash. omarchy-migrate runs it with
bash -euo pipefail, and the migration depends on that: it is what stops
a failed limine-mkinitcpio before the marker is written, so the next
update tries again. The stand-in rebuild could not fail, so nothing held
that promise.

The test now uses the same options and adds the case: a rebuild that
fails ends the migration with an error and leaves no marker, and the
next run rebuilds and marks it.
