dix: offset touch root coordinates by ScreenRec origins (#86655) 

For two ScreenRecs abs pointer positioning was working fine, but touch events
stuck to the lower/right edge on any screen but the one with a 0/0 origin.
Cause is a missing offset by the screen coordinates, causing the root
coordinates in the event to desktop-wide, not screen-wide.

Offset properly, just like we do for pointer events.
