Subject: [PATCH] Don't evaluate overlays on master

master is only used in the context of `pkgs/override.nix`
and `unstableModulesPath`
and only within `./hosts`

Since overlays exists that are incompatible between nixos and master
at evaluation time (sic!), this together with #77 avoids evaluating
overlays against master all together.
