drm/xe: Include build directory

When doing out-of-tree builds with O= or KBUILD_OUTPUT=, it's important
to also add the directory where the target is saved. Otherwise any file
generated by the build system may not be available for other targets
depending on it.

The $(obj) is added automatically when building the entire kernel,
but it's not added when M=drivers/gpu/drm/xe is added.
