    gtkspinbutton: Group up/down button gestures with self
    
    We are adding click gestures on the up/down buttons, but can't let
    the GtkButton built-in ones prevent ours to run.
    
    As the saying goes, if you can't beat them, join them. Group the
    spinbutton and GtkButton gestures together, so it's irrelevant which
    gets called first and ends up winning.
