Simplify touch-event handling a bit.

Browse Source 
Discussion to this in https://sourceforge.net/p/irrlicht/patches/322
Basically last solution caused problems as it send fake-mouse events on top of touch-events.
For now we can probably just enable touch-events and clear masks for everything else for all devices
as we only use the XInput2 events for touch-event handling and nothing else.
At least not noticing conflicts with rest of X11 input so far and user TheBrokenRail said this works for him.
