Subject: [PATCH] ci: backport mkosi CI configuration from upstream
Notes:
- on RHEL 9 we don't have vsock support in systemd, so we have to fall
back to some "older" checks (i.e. pre-6aca147f82).
- our systemd-repart doesn't automatically fall back to Format=swap
for Type=swap partitions, so we have to do that explicitely
- don't pull in sd-resolved and sd-networkd, since the former needs
some extra configuration to work alongsideNM, and we don't
build the latter at all on RHEL 9
RHEL-only
Related: RHEL-27512
