util: if present, fallback to `toString` using the %s formatter
This makes sure that `util.format` uses `String` to stringify an object
in case the object has an own property named `toString` with type
`function`. That way objects that do not have such function are still
inspected using `util.inspect` and the old behavior is preserved as
well.
