Title: Add `--json` argument to `nix-instantiate`

This is complementary to ``--xml`` and uses already existing functionality.

I think it's useful for using with external tools, i.e. to convert *nix* to json, and parse with json parser. (BTW, works well with `json_pp`, or does *nix* has pretty-printer of it's own?)
