nixos/postfix: fix default postfix config 

`services.postfix.config` is now correctly merged with the default attrset
specified in the module. Some options that are lists in postfix also
have to be lists in nix to be merged correctly. Other default options are
now set with `mkDefault` so they can be overridden via the module system.
