    route(8): Fix routename() for AF_LINK addresses with sdl_index
    
    The link_ntoa() function is able to handle such link addresses with zero
    lengths but only 'sdl_index', so route(8) would print an empty string
    for some RTA_GATEWAY and RTA_IFP sockaddrs in the monitor output.
    
    Fix routename() to correctly print such addresses by copying the code
    from netstat(1).
