k8s cannot start pods after revendoring virtcontainers with latest changes

[chavafg]

From #196, we started getting k8s issues. cc-runtime start gets hanged:

From the cc-proxy journal this seems to be the error:

@amshinde suggested to test #196 with latest code on the clearcontainers/agent repository, which seems to have a fix for the error above. But latest code from agent also has issues when creating pods: https://github.com/clearcontainers/agent/issues/182
