ceph.spec.in: do not install Ceph RA on systemd platforms

[smithfarm]

The ceph-resource-agents package consists of two RAs: the "Ceph RA" (which includes RAs for OSD, MON, and MDS) and the "RBD RA". Since the Ceph RA wraps the Ceph sysvinit script, it cannot be used on systemd-based platforms. The RBD RA is OK on systemd.

Continuation of #7810

I manually tested this by building in OBS and installing the ceph-resource-agents RPM on openSUSE Tumbleweed. Confirmed that only the RBD RA is installed.

@ktdreyer Who should I ask to review this? The issue it is fixing is as follows: the Ceph Resource Agents are useless on systemd platforms because they wrap /etc/init.d/ceph.

Tore down that run after looking at http://pulpito.ovh.sepia.ceph.com:8081/?branch=jewel and seeing that it would be affected by http://tracker.ceph.com/issues/15123 which is fixed by #8073

Rolled a new wip branch including the fix for this issue. New upgrade/infernalis-x run in OVH:

lgtm in principle; feel free to merge once you're satisfied with the testing.

Do you think that is sufficient to demonstrate that it doesn't break anything?
