debian: ceph-dbg steals ceph-objectstore-tool from ceph-test-dbg (take 2)

968573b8930a7c8485bf53e3a989ce2f7d0a2fff incorrectly backported
6f11fbf41fab10924b1e0e41fcf27864779d4073. It should instead reflect that
ceph-dbg in 0.94.2 and above will break ceph-test-dbg in all versions
prior to 0.94.2.

In other words, 0.94-XXXX being lower than 0.94.1, upgrading from
0.94.1 to 0.94.2 will not notice that ceph-dbg breaks ceph-test-dbg.

$ dpkg --compare-versions 0.94-XXXX lt 0.94.1 && echo yes || echo no
yes
$ dpkg --compare-versions 0.94.2 lt 0.94.1-xxx && echo yes || echo no
no
