The big rewrite of rhel9 distro omitted installing s390utils-base into the
buildroot. This caused the org.osbuild.zipl.inst stage because of missing
/usr/sbin/zipl.
This commit introduces s390utils-base back into the buildroot which fixes
building of the s390x images.
I verified it by building the RHEL 9.1 qcow2 image and booting it using
libvirt.

GCE requires an archive with specific (tar) options, so we should have a
platform format defined separately for it.
Add the GCE image types to the x86_64 arch using the new platform
format.
These objects describes the hardware an image runs on. Including
- architecture
- bootloader
- required firmware
Use the platform abstraction to move firmware packages out of the package set
definitions.
