Deb: make server core package breaks/replaces earlier client packages

This is required, as the innochecksum binary has moved package.
Without this change the following error would be emitted:

  Unpacking mariadb-server-core-10.2 (10.2.3+maria~jessie) over (10.2.2+maria-1~jessie) ...
  dpkg: error processing archive /var/cache/apt/archives/mariadb-server-core-10.2_10.2.3+maria~jessie_amd64.deb (--unpack):
    trying to overwrite '/usr/bin/innochecksum', which is also in package mariadb-client-10.2 10.2.2+maria-1~jessie
