nixos/rspamd: Add options for postfix integration

The `rmilter` module has options for configuring `postfix` to use it but
since that module is deprecated because rspamd now has a builtin worker
that supports the milter protocol this commit adds similar `postfix`
integration options directly to the `rspamd` module.
