Add Xorg driver ABI dependencies

Hi,

The xserver driver ABIs frequently change and as such are versioned. It's entirely possible to build an image with an Xserver with ABI 13 but drivers using ABI 11, and in this situation the server won't load the modules. These ABI versions have no relationship to the package version so the existing dependencies can't be made stricter.

The solution Debian (and probably others) take is to add versioned Provides to the server, and dependencies on those provides in the drivers. Then ABI version mismatches become package dependencies errors and are caught at image construction time, not boot time.
