test: Consolidate offline user podman hack

Re-drop the "run VM online" hack for Fedora CoreOS. It's enough to apply
our "add dummy iface" hack like we do on non-CoreOS images -- we just
forgot to pass our `VM_CUSTOMIZE_FLAGS` there.

This regression has reached CentOS 9 Stream now, so this workaround is
necessary there as well.

As the original upstream bug is closed, add a reference to the Fedora
bugzilla.
