Injecting `LD_LIBRARY_PATH` to the Python runtime environment is great to bypass the need of having to patch non-nix binaries loaded into that environment, however it breaks down, when Python executes any other program not compiled for the given Nix system, e.g. a shell script via `subprocess`. To work this around, `devenv` will inject a `pth`[^1] file to the virtual environment it creates, which mangles the `LD_LIBRARY_PATH` variable, undoing any changes to it made by `devenv` but preserving changes from other sources. Fixes cachix#1111 [^1]: https://docs.python.org/3/library/site.html

I am unsure what the best way would be to integrate this, bit I think the approach in general is sane. I am tested only the poetry case currently.
