gdk/wayland: Unset GDK_BUTTON1_MASK on proximity_in

In some circumstances (e.g. activating with a stylus something that
closes a window), we can receive zwp_tablet_tool.proximity_out without
receiving a zwp_tablet_tool.up beforehand.

In those cases, we are not expecting neither .up nor .button, so
reset the stylus device button modifiers on proximity_out.
