project-lakitu: Wait for xtables lock
All iptables/ip6tables commands that we run should be run with "-w".
This tells iptables to block until the xtables lock is available.
Since iptables commands are usually fast and often run without any other
external synchronization, using "-w" will avoid erroneous iptables
failures due to lock contention.
