drm/xe: Fix build with KUNIT=m

Browse Source 
Due to the current integration between "live" xe kunit tests and kunit,
it's not possible to have a build with the following combination:

	CONFIG_DRM_XE=y
	CONFIG_KUNIT=m

... even if kconfig doesn't block it. The reason for the failure is that
some compilation units are pulled in xe.ko:

	drivers/gpu/drm/xe/xe_bo.c:#include "tests/xe_bo.c"
	drivers/gpu/drm/xe/xe_dma_buf.c:#include "tests/xe_dma_buf.c"
	drivers/gpu/drm/xe/xe_migrate.c:#include "tests/xe_migrate.c"
	drivers/gpu/drm/xe/xe_pci.c:#include "tests/xe_pci.c"

Those files shouldn't use symbols from kunit, which should be reserved
to the tests/*_test.c files. Detangling this dependency doesn't seem
very straightforward, so fix the immediate issue instructing kconfig to
block the problematic configuration.
