pknock: disallow running peer_gc too early

Browse Source 
It is no longer possible to specify gc_expir_time with a time lower
than its default value (65000 msecs). This is to avoid running
peer_gc() earlier than 1 minute [well, 65 s actually] in the future,
which would otherwise render anti-spoof protection in SPA mode
non-functional.

- added reworked xt_pknock module
Changes from pknock v0.5:
- pknock: "strict" and "checkip" flags were not displayed in `iptables -L`
- pknock: the GC expire time's lower bound is now the default gc time
(65000 msec) to avoid rendering anti-spoof protection in SPA mode useless
