buildLuarocksPackage: save luarocks config as derivation (#269402) 



* buildLuarocksPackage: save luarocks config as derivation

while debugging luarocks packages, it's exhausting to have to build
them, look at what random folder they've been built to finally look for
their config.


With this you can run
    nix build lua51Packages.plenary-nvim.configFile -f . 

and infer what luarocks will do.

* Update pkgs/development/interpreters/lua-5/build-luarocks-package.nix
