Update ip6_route_multipath_add to consider the ONLINK setting coming from rtnh_flags. Each loop over nexthops the config for the sibling route is initialized to the global config and then per nexthop settings overlayed. The flag is 'or'ed into fib6_config to handle the ONLINK flag coming from either rtm_flags or rtnh_flags.
