Fixes #3793.

Enabling BCP38 causes an iptables rule to be inserted before this rule:
ACCEPT     all  --  anywhere             anywhere             ID:66773300 ctstate RELATED,ESTABLISHED

This makes all forwarded packets go through the BCP38 ipset match, which slows
down download speed from 440 Mbit/s to 340 Mbit/s.

Only apply BCP38 match rules if state is NEW.

Bump package version.
