[Nix-dev] builderDefsPackage and propagatedBuildInputs

[Domen Kožar]

This is exactly why I created https://github.com/NixOS/nixpkgs/issues/4210
and would like to get rid of many ways to declare a package. I'd say plain
mkDerivation is encouraged and whenever I upgrade a package using
builderDefsPackage, I'd convert it into plain mkDerivation function.
