fw: use RetxSuppressionExponential in best-route

Retransmission suppression algorithm of best route strategy
is changed from fixed interval to exponential backoff.
This is a semantical change which requires an increment of the
strategy's version number from 2 to 3.
Version 2 is not retained because it's mostly same as version 3.
