Add pkgs to use nixpkgs-default easily (#602)
Currently if we want to use nixpkgs-default and nixpkgsAgs it is
a bit painful. With this change:
```
nix-build -E 'let h = import ./. {}; in (import h.sources.nixpkgs-default h.nixpkgsArgs).haskell-nix.tool "hlint" "3.1"'
```
becomes
```
nix-build -E 'pkgs.haskell-nix.tool "hlint" "3.1"'
```
