This reverts commit b67ee6e861.

https://github.com/NixOS/nixpkgs/issues/202244

error: a string that refers to a store path cannot be appended to a path, at /etc/nixos/nix/nixos-unstable/lib/sources.nix:193:30

appears to happen when there's a nixpkgs git submodule

> So one of the things that is different for a git submodule is that the .git folder isn't a folder, it's a textfile that contains (in my case) this:

> $ cat nix/nixos-unstable/.git
> gitdir: ../../.git/modules/nixpkgs
