netfilter: xt_LED: fix too short led-always-blink
If led-always-blink is set, then between switch led OFF and ON is almost zero time. So blink is invisible. This use oneshot led trigger with fixed time 50ms witch is enough to see blink. Signed-off-by: Jiri Prchal <jiri.prchal@aksignal.cz> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
