rpm: adjust ceph-{osdomap,kvstore,monstore}-tool feature move

this is the rpm's counterpart of debian/control changes related to the
ceph-{osdomap,kvstore,monstore}-tool feature move. see ceph#19328 and ceph#19356.
the commit introducing this move is 6dba25e. and

$ git describe 6dba25e
v12.2.2-8-g6dba25e39d

so the first release that have this change is 12.2.2-8. in other words,
ceph-{base,osd,mon} >= 12.2.2.8 cannot co-exist with ceph-test < 12.2.2-8
in the same system. so we let ceph-test Requires ceph-common with the
same version. and since ceph-{osd,mon} Requires ceph-base with the same
version, and ceph-base Requires ceph-common with the same version, so by
tiering ceph-test with ceph-common with the same version, we enforce
this restriction.
