Subject: [PATCH] uv: Build as a standalone without Python

Using `buildPythonPackage` triggers dependency propagation, meaning that using `uv` with `nix-shell` results in a a shell with the `uv` Python input in it.
This is problematic for development usage where you only want the one specified version.

Often this design bug in the Python package builders is worked around by deleting `$out/nix-support/propagated-build-inputs`, but since `uv` is written in Rust and can be built without a Python interpreter so it's better to just build without a Python interpreter.
