    dnd: Remove emission of fake button release event
    
    Nowadays (and for quite some years now) we rely on GdkEventGrabBroken
    events to be received. This fake button event seems a remnant of
    the early Gtk 2.x days, and is currently even inconsistent with our
    event delivery model, so just remove it.
