This allows separating the use of nixgl.auto.nixGLDefault from the
location where we pass nvidiaHash to provide a pure instantiation.
Without this usage of nixgl.auto.XXX is always impure.
Also reuse nixgl.auto in top when nVidia is forced instead of
duplicating its definition, because that leaves the possibility for
bugs when these duplicates aren't in sync.
