    Host our own iptables tarball on people.gnome.org
    
    netfilter.org has been down for two days in a row, so it has lost the
    right to be a tarball source for GNOME. I failed to find iptables
    tarballs hosted elsewhere on the internet, so we will use Debian's
    .orig tarball instead. But we have to rehost it ourselves, because
    Debian does not offer HTTPS.
    
    We'll also move popt to a new location.
