nix: fix CUDA build - replace deprecated autoAddOpenGLRunpathHook
The CUDA nix build broke when we updated nixpkgs in
8cd1bcfd3fc9f2b5cbafd7fb7581b3278acec25f. As far as I can tell all
that happened is cudaPackages.autoAddOpenGLRunpathHook got moved to
pkgs.autoAddDriverRunpath. This commit fixes it.
