iptables: state match incompatibilty across versions
As reported in Debian bug #718810 [1], state match rules added in < 1.4.16
iptables versions are incorrectly displayed by >= 1.4.16 iptables versions.
Issue bisected to commit 0d701631 (libxt_state: replace as an alias to
xt_conntrack).
Fix this by adding the missing .print and .save functions for state match
aliases in the conntrack match.
