[pygobject] Drop gi.overrides.overridefunc()

[Martin Pitt <martinpitt src gnome org>]

commit 1dc2bc9f65669417ae1964d70b85f115928b2963
Author: Martin Pitt <martinpitt gnome org>
Date:   Fri Mar 1 14:04:34 2013 +0100

    Drop gi.overrides.overridefunc()
    
    This just adds an unnecessary extra function call and is not really needed.
    Drop it from the only remaining function which uses this (Gtk.main_quit) and
    drop overridefunc().
