Detect iptables version and avoid --wait

[bprashanth]

Logs seem to indicate it isn't available on 1.4.14 which comes with a stock gce vm.

@jonboulle since coreos/go-iptables#12 is merged can we just bump the dependency to move forward?

[jonboulle]

Yes AFAICT

Having enormous trouble with godep to update dependencies... what version of godep are you guys using where it works to update?

[jonboulle]

Almost always want to use the very latest version of godep.

Okay I figured out this godep issue (I think) and have another open issue #406 which blocked me from updating the coreos/go-iptables dependency using godep. Once that PR is merged, I have another fix on a branch to update go-iptables with the fix needed. I really need a critical eye on #406 if anybody can help me out here.
