Fix this by reverting the select to a dependency. Make sure the GPU buddy allocator can be tested without enabling another driver that uses DRM_BUDDY by making GPU_BUDDY visible if KUNIT is enabled. The page based buddy allocator for GPU memory is only used by DRM. Hence add a dependency on DRM to GPU_BUDDY, to prevent asking the user about this code when configuring a kernel without DRM support.
