Subject: Nix: Use nixos-unstable for nodejs on Linux

My Laptop uses the stable channel for the system by default, but also
has the unstable channel available for when I need it.  NodeJS 8 isn't
available on the stable channel, so manually import nixos-unstable.

Other machines shouldn't be affected, as they're using nixpkgs
unstable on other OSes.
