tcwg-update-*-containers.sh: Restart containers only on image update
Restart host, jenkins node and llvmbot containers only if underlying
docker image has changed. This allows us to simplify management of
persistent infrastructure containers (host, jenkins node and llvmbot
containers) by triggering update job, say, every day, instead of
monitoring dockerfiles.git repo for changes.
