[Intel-gfx] [PATCH 2/2] configure.ac: Do not include `x11-xcb`, `xcb-dri2` and `xcb-aux` in `XVMCLIB`

[Chris Wilson]

The first patch looks fine (and I've applied it, thanks), but I'm not
convinced this one is safe.

Notice that the warning is only generated for I810XvMC and not for
IntelXvMC which does use the DRI2 interface to pass along video objects.
Since XVMCLIB is shared between the two we would need to split out the
I810XvMC dependencies from the IntelXvMC set first.
