udev: input_id: tag pointing sticks as ID_INPUT_POINTINGSTICK
Also referred to as trackpoint, trackstick. These are marked by recent kernels
through an input prop. Forward that prop as udev property so userspace can
easily determine whether there is a pointing stick present.
These devices were previously marked as ID_INPUT_MOUSE, for backwards
compatibility we keep that in place, the new property is an addition.
