Without the change the `python3Packages.faiss.passthru` are broken:

    $ nix repl -f.
    nix-repl> python3Packages.faiss.passthru
      cudaPackages = «error: attribute 'cudaPackages' missing»;
      cudaSupport = «error: attribute 'cudaSupport' missing»;
      pythonSupport = «error: attribute 'pythonSupport' missing»;
