amdgpu: Add new function to get fd.

Dual purpose:
 - The drm fd dedupe functionality confuses the radeonsi
   amdgpu winsys if radeonsi isn't the first thing opening
   the device. By exposing the fd we can detect this case.
 - For a common mesa Vulkan sync objects implementation
   with syncobj. (notable: no buffer allocation)

Both shouldn't interferece with libdrm_amdgpu functionality
though it does somewhat piece the abstraction of the library.
