Without this patch merging options like
services.xserver.windowManager.xmonad.extraPackages
results in the evaluation error:
error: value is a list while a set was expected, at nixpkgs/lib/options.nix:77:23
With this patch we get the desired merging behaviour that just concatenates the
resulting package lists.
