The iptables example was added in commit d2f26037a38a (netfilter: Add
documentation for tproxy, 2008-10-08), but xt_socket 'transparent'
option was added in commit a31e1ffd2231 (netfilter: xt_socket: added new
revision of the 'socket' match supporting flags, 2009-06-09).
Now add the 'transparent' option to the iptables example to ignore
non-transparent sockets, which is also consistent with the nft example.
