The ConsoleKit module is loaded by default from the default.pa
configuration file, but its initialization fails because Buildroot has
no ConsoleKit package yet. This breaks per-user pulseaudio daemon.
The default.pa configuration load module-console-kit only when it
exists. Remove module-console-kit to fix pulseaudio per-user startup.
