firefoxWrapper has become unfree

[peti]

6ed1d9f seems to have added a dependency in faac, which is unfree. As a result, Hydra can no longer build firefoxWrapper (and some other tools):

in job ‘audacious.x86_64-linux’:
Package ‘faac-1.28’ in ‘/nix/store/ndky2g5zmafg173n14whykhqzbcw8a7j-git-export/pkgs/development/libraries/faac/default.nix:26’ has an unfree license ‘{"free":false,"fullName":"Unfree redistributable","shortName":"unfreeRedistributable"}’ which is not whitelisted, refusing to evaluate.
For `nixos-rebuild` you can set
  { nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this.
For `nix-env` you can add
  { allowUnfree = true; }
to ~/.nixpkgs/config.nix.
