The essential commands from the NixOS installer as a package

With this package, you get the commands like nixos-generate-config and
nixos-install that you would otherwise only find on a NixOS system, such
as an installer image.

This way, you can install NixOS using a machine that only has Nix.

It also includes the manpages, which are important because the commands
rely on those for providing --help.
