    hurd if_index: Explicitly use AF_INET for if index discovery

    5bf07e1b3a74 ("Linux: Simplify __opensock and fix race condition [BZ #28353]")

    made __opensock try NETLINK then UNIX then INET. On the Hurd, only INET

    knows about network interfaces, so better actually specify that in

    if_index.
