backends/x11: Fix access to WacomDevice

Browse Source 
At some point we crossed the streams... In a short timespan we had
1f00aba92c merged, pushing WacomDevice to a common parent object,
and dcaa45fc0c implementing device grouping for X11.

The latter did not rely on the former, and just happened to
merge/compile without issues, but would promptly trigger a crash
whenever the API would be used.

Drop all traces of the WacomDevice internal to MetaInputDeviceX11.
