iptables/extensions: make bundled options work again
When using a bundled option like "-ptcp", 'argv[optind-1]' would
logically point to "-ptcp", but this is obviously not right.
'optarg' is needed instead, which if properly offset to "tcp".
Not all places change optind-based access to optarg; where
look-ahead is needed, such as for tcp's --tcp-flags option for
example, optind is ok.
