pkg/serializer: support primitive user types in interfaces

Add handling of user types that has underlying primitive types.
Consider:

	type T int
	var obj interface{} = T(42)

T has kind reflect.Int. But if we serialize obj as just "42",
it will be turned into plain int.
Detect this case and serialize obj as "T(42)".
