Upgrade Docker, from 18.09.6 to 18.09.7

Don't disable other container engines when --vm_driver=none

which can be picked up during integration testing.

I opted to do it this way because the locally built gvisor image wasn't
being picked up by minikube, because the docker daemon wasn't
configured, since minikube isn't up and running yet. Even if the docker daemon was configured to point to
minikube, we wouldn't be able to build the gvisor-image from the test
itself.
