[debian] fix dpkg error on upgrade from << 0.8.4
The problem was triggered by the fact that the file deejayd/xmlobjescts.py
changed from the deejayd-client binary package to the deejayd binary package.
This patch forces a deconfigure of the deejayd-client package before the new
version of deejayd is installed, thus dpkg does not complain about this file
belonging to both deejayd and deejayd-client.
