    gdebugcontroller: Drop dup_default() method as it’s broken
    
    If `GDebugControllerDBus` remains as the only, or default,
    implementation of `GDebugController`, `dup_default()` cannot work.
    `GDebugControllerDBus` requires a `GDBusConnection` at construction
    time, which the `GIOModule` construction code can’t provide it.
    
    Either we use a default D-Bus connection (but which one? and how would
    it be changed by the user later if it was the wrong one?), or delegate
    singleton handling of the `GDebugController` to the user.
    
    The latter approach seems more flexible.
