python3.pkgs.buildsetupcfg: Remove function from python-packages-base.nix

This function is not, and never have been, used anywhere inside nixpkgs, outside of bootstrapping setupcfg2nix itself.
It was added in https://github.com/NixOS/nixpkgs/pull/38778 by @shlevy.

It has no out-of-tree users on Github either. External breakage is not expected.
