Subject: [PATCH] break: change how nixpkgs is passed to the project

Evaluating nixpkgs is quite expensive and should be done only once if
possible. This allows to pass a correctly-configured instance of nixpkgs
(with allowUnfree = true).

Unfortunately this requires to break the current interface.
