nixos-*: init as package

Move all the nixos-* scripts from the nixos distribution as real
packages in the pkgs/ package set.

This allows non-nixos users to run the script as well. For example,
deploying a remote machine with:

    nixos-rebuild --target-host root@hostname --build-host root@hostname
