graphics/mesa-devel: apply 36049d3 to Vulkan with VAAPI=off

On Intel GPUs VA-API is implemented by libva-intel-{,media-}driver but
Vulkan Video is implemented by Mesa. VAAPI in mesa-devel depends on
AMD drivers which in turn brings heavy llvm* dependency, so may not be
desirable on Intel-only or Intel+NVIDIA systems.
