multi: explicitly signal final hop in pack hop payload

Browse Source 
Previously, we'd use the value of nextChanID to infer whether a payload
was for the final hop in a route. This commit updates our packing logic
to explicitly signal to account for blinded routes, which allow zero
value nextChanID in intermediate hops. This is a preparatory commit
that allows us to more thoroughly validate payloads.
