debian: fix package relationships after 40caf6a6

debian: fix package relationships after 40caf6a6

we have issues when running upgrade tests:

dpkg: error processing archive /var/cache/apt/archives/ceph-osd_13.0.0-2201-g6cc0b41-1trusty_amd64.deb (--unpack):
trying to overwrite '/usr/bin/ceph-osdomap-tool', which is also in package ceph-test 10.2.10-14-gcbaddae-1trusty

in 40caf6a6, we moves some tools from ceph-test out into ceph-osd,
ceph-mon and ceph-base respectively. but didn't update the relationships
between these packages accordingly. this causes the upgrade failure.

see https://www.debian.org/doc/debian-policy/#document-ch-relationships
for more details on "Breaks" and "Conflicts".

the reason why the package version to be replaced/conflicted is 12.2.2
is that: i assume that this change will be backported to luminous, and
the next release of it will be 12.2.2 .
