Lift canceled touch inputs

Browse Source 
If a touch input gets turned into a palm (by setting ABS_MT_TOOL_TYPE to
MT_TOOL_PALM), libinput will emit a cancel event instead of the normal
up event. The xorg wrapper needs to be able to handle a canceled touch
and lift it, otherwise these inputs will never get lifted and will stick
around forever.
