test: Add bootc image preparation

We want to test deploying cockpit rpms in bootc images. This will
prevent hiccups like
#21201 in the future
and also test a lot of OS subsystems.

The centos-9-bootc bots image includes its own deployment container
image, so we can easily derive an image with our locally built RPMs
included.
