Packaging request: nitrocli (tests contain hardcoded python-path)

[Jauchi]

Project description
Hello! I would like to request nitrocli, a cli-alternative to nitrokey-app.
It's written in Rust, I tried a little myself already (my first nix package), but the python stuff is going over my head.

This gets to the testing stage, where it fails.
I assume it fails because the testing creates and executes a python script, which won't work because python is not in the path (resulting in file not found):

{ libusb1, hidapi, lib, rustPlatform, fetchFromGitHub }:
rustPlatform.buildRustPackage rec {
  pname = "nitrocli";
  version = "0.4.1";

  src = fetchFromGitHub {
    owner = "d-e-s-o";
    repo = "nitrocli";
    rev = "8a8250f262100a95164a7b0ff8e1ea7d5c17e3a6";
    sha256 = "1lvl6z9xh479dzpdv11wnxdr9amm8np2037bg79i6im6y23jyn4g";
  };

  cargoSha256 = "0k58bckxxc7kjj3swsm5gg2pvxc7dn7k5s0bv1lajx9gxrhrb04n";

  buildInputs = [
    libusb1
    hidapi
  ];

  meta = {
    description = "A command line tool for interacting with Nitrokey devices";
    homepage = "https://github.com/d-e-s-o/nitrocli";
    license = lib.licenses.gpl3Plus;
  };
}

This is the problematic part is right here: https://github.com/d-e-s-o/nitrocli/blob/97fd3be6375c8158ea58e4d9260f4523753d4c10/src/tests/run.rs#L297
The nicest solution would probably be adding python to the environment at build time, but I don't know how (or if) I should even do that.

Use substituteInPlace to replace the shebang with the python shebang like is done here https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/science/logic/symbiyosys/default.nix#L35
