[PATCH libinput] udev: drop the version field in device groups

[Benjamin Tissoires]

The version field is a per device information. We have
no guarantees a touchscreen and a tablet device will share
the same version of the firmware (especially if both
firmwares are from different vendors).

Fixes the touch arbitration for the Dell Canvas 27
