Recently, the Minikube gate script was modified to support Ubuntu Bionic
[0]; however, the change made the script incompatible with Ubuntu Xenial
because libxtables12 is not available on Ubuntu Xenial. OpenStack-Helm
still supports Ubuntu Xenial, and this script should too.
This change modifies the gate script to install iptables instead of
libxtables12. The iptables package depends on libxtables11 on Ubuntu
Xenial and libxtables12 on Ubuntu Bionic, so this achieves the same
result.
