Clear EV_ABS_V_USE_TOUCH for devices without a touch button

Browse Source 
VMware's absolute pointing device does not have a pressure/touch button.
Although evdev correctly recognizes this, it sets "use_touch" for X and Y axes
regardless of the touch button. This patch clears the USE_TOUCH flag for the X
and Y axes if the device does not have a touch button.
