Treat BTN_[0-2] as LMR buttons on devices that do not advertise BTN_LEFT,
BTN_MIDDLE, BTN_RIGHT (e.g. 3Dconnexion SpaceNavigator).
Otherwise, treat BTN_[0+n] as button 5+n. Note: This causes duplicate
mappings for BTN_0 + n and BTN_SIDE + n.
This also fixes a bug where we could end up with negative button numbers after
trying to map BTN_0.
