x11: get the tool type from the wacom driver properties

Browse Source 
Any wacom device currently sets the tool type to UNKNOWN. The wacom driver has
a property that exports the tool type as one of stylus, eraser, cursor, pad or
touch. Only three of those are useful here but that's better than having all
of them as unknown.
