[Nix-dev] Shape configuration.nix differently

[Manuel Pages]

Dear Nicolas, I have already read the diffs and lib/modules.nix
and am sad. I don't have enough knowledge to criticize those changes
though.

Dear Jeffery, this way my "submodules" are shaped as a first-order
functions (Submodule :: Set -> Set), with your approach we
actually have (Submodule :: Set -> (Set -> Set)) which is fine by
me and I'll use this approach for now.

Thank you very much!
