[PATCH net-next v2 09/13] tools/net/ynl: Move formatted_string method out of NlAttr

[Donald Hunter <donald.hunter@xxxxxxxxx>]

The formatted_string() class method was in NlAttr so that it could be
accessed by NlAttr.as_struct(). Now that as_struct() has been removed,
move formatted_string() to YnlFamily as an internal helper method.
