drag-action: Re-use press_button in emit_drag_end()

Since emit_drag_end() can be called from a MOTION event capture we
cannot call clutter_event_get_button(). We should, instead, use the
press_button value because if we're emitting ::drag-end it means we
also emitted ::drag-begin and the value is valid.
