    routing: Make ip[6]_tryforward() FIB-aware for local traffic
    
    `ip_tryforward()` and `ip6_tryforward()` checks whether the destination
    address is local or not without considering if it belongs to the current FIB.
    If the destination is local but not in our FIB, forward it instead
    of returning it to ip_input().
