[PULL 1/6] ui/gtk: Ignore 2- and 3-button press events

[Gerd Hoffmann]

From: "K. Lange" <klange@toaruos.org>

GTK already produces corresponding GDK_BUTTON_PRESS events
alongside 2BUTTON and 3BUTTON_PRESS events. The 2BUTTON and
3BUTTON_PRESS events were incorrectly being interpreted and
passed to guests as button release events.
