Fixes a problem building a NixOS options file on Darwin
Bumps nixpkgs as it is required for builds to work on current versions of macOS.
Bumps naersk so that it works with current nixpkgs
Adds support for nix-darwin options
I tested getting NixOS options from Darwin and getting nix-darwin options from NixOS and it seems to be working ok.
PS
As a semi-related aside, I also rebased the @elkowar fork on upstream to make it work with this (due to required newer versions as mentioned above). It took some conflict resolution but nothing too bad and it seems to work ok (see here).
Any reason not to upstream that?
It looks like an obvious improvement over not having those features...
