fw: delegate sending Nack-Duplicate to forwarding strategy
This commit introduces a new strategy trigger (onInterestLoop) that
is invoked when a duplicate Interest is received. The default behavior
of the new trigger is to send a Nack as before. We also modify the
MulticastStrategy to override onInterestLoop and skip sending the Nack.
