systemd: avoid creating an empty user.conf
Due to the defaults in `systemd.user.settings`, the default value when there are no settings explicitly set is `{ Manager = { }; }`. This means an empty file is created even when `systemd.user.settings` is never used in home-manager configuration. Since user’s `user.conf` is preferred to the global `/etc/systemd/user.conf`, this can cause any values set in the latter to be discarded.
