Subject: [PATCH] pkgs/config.nix: Fix infinite recursion when freeform config
 is strict in pkgs

https://github.com/NixOS/nixpkgs/issues/175196

The loop involved:

 - pkgs is strict in the config.nix freeformType's produced attrNames,
   as these are included in the config.
 - the attrNames were strict in all the direct attrValues, because of
   scanning for `mkIf`s.

`lazyAttrsOf` removes proper `mkIf` support, which we don't need here.
