Florian Westphal 37d220b58d selftest: netfilter: add test case for unreplied tcp connections
TCP connections in UNREPLIED state (only SYN seen) can be kept alive
indefinitely, as each SYN re-sets the timeout.

This means that even if a peer has closed its socket the entry
never times out.

This also prevents re-evaluation of configured NAT rules.
Add a test case that sets SYN timeout to 10 seconds, then check
that the nat redirection added later eventually takes effect.

This is based off a repro script from Antonio Ojea.
