    gi/pygobject-external.h: Remove GCCism
    
    We can use G_GNUC_UNUSED from GLib that does the same purpose of
    __attribute__ ( (unused)) when we are using a GCC that provides this.
    
    The GLib headers that defines that macro should have already been included
    before this header is included (due to use of gboolean).
