drm/xe: Fix KUnit build issues
The dependency chain for KUnit is broken: it currently misses DEBUG_FS and DRM_FBDEV_EMULATION.
Without that, trying to build tests fail.
After the patch, KUnit works again:
$ ./tools/testing/kunit/kunit.py run --arch x86_64 --kunitconfig drivers/gpu/drm/xe/.kunitconfig
