    Add iptables metadata marking rule on router init

    Move the iptables metadata marking rule earlier in
    router init, that way any stray metadata requests
    that arrive before the filter metadata redirect rule is
    installed will just be dropped. We do this irregardless
    of whether we will be running the metadata proxy.

    Partial-bug: #1735724
