images/server: enable ceph on centos9 nightly (stable build)

Enable the centos storage sig repo to get ceph dependencies on centos 9.
Currently the ceph module doesn't function correctly but once a fixed
version of ceph reef is available the 'nightly' centos images should
be able to use the vfs ceph module too.
