https://github.com/NixOS/nixpkgs/pull/340162 introduced `autoPatchelfHook` as it's own top-level attribute.
This also made it use the Nixpkgs Python build infrastructure, which relies on dependency propagation, leaking Python as a dependency into many builds erroneously.
This change uses a `withPackages` constructed environment instead, and manually patches the script shebangs, not triggering the `buildPython*` dependency propagation mechanism
