nixos/home-assistant: convert to rfc42 style settings
After this change users with non-declarative configs need to set `services.home-assistant.config` to an `null`, or their `configuration.yaml` will be overwritten. The reason for this is that with rfc42 style defaults the config attribute set will never be empty by default.
