debian: fix package relationships after d3ac8d18

d3ac8d18 moves ceph-client-debug from ceph-test to ceph-base without
updating the package relationships between the two involved packages.
which results in:

dpkg: error processing archive /var/cache/apt/archives/ceph-test_12.2.1-241-g43e027b-1trusty_amd64.deb (--unpack):
 trying to overwrite '/usr/bin/ceph-client-debug', which is also in package ceph-base 10.2.10-14-gcbaddae-1trusty
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
