Goal is to improve separation between packages and utilities.
Can help with autocompletion/navigate nixpkgs faster.
Also it will help standardize how LUA_PATH is exported across packages,
so that one can more easily make lua changes across nixpkgs (for
instance changing where lua modules are installed).
