backends: Add envvar to disable wacom configuration

Browse Source 
People that relied on xsetwacom to configure their tablets used to get
away with this by disabling the wacom g-s-d plugin prior to running
their scripts. This is not possible anymore with mutter managing device
configuration.

Given that X11 shall not go away soon and there's a core of stubbornly
accustomed users, provide a MUTTER_DISABLE_WACOM_CONFIGURATION envvar
to provide *some* way to do this.
