[gdm] daemon: Drop manager bus watching code

[Ray Strode <halfline src gnome org>]

commit 7f646470e16afeef3c3e23853daea0d6012118e8
Author: Giovanni Campagna <gcampagna src gnome org>

    daemon: Drop manager bus watching code
    
    GdmManager watches the system bus to see whenever a service
    leaves.  The intent of the code is to stop managing displays
    associated with slaves that have disappeared.
    
    The code wasn't ever finished, though, so drop it for now.
    
    It will be easy to add back in a different way after GdmManager
    has been ported to GDBus.
