Fixed some issues in the container lists in the Makefile and in
containers.cfg. An obscure KVM bug was not digesting host-model
properly on some architectures causing a kernal panic on boot.
In order to work around that bug, host-passthrough will be used
until KVM is fixed in ubuntu16.04. This bug doesn't exist in
ubuntu14.
