Launch script will now tag instead of build images

Made this change to shift the building of the Dockerfile away from the
helper script. Instead the build will now be done by invoker scripts.
Then doing the helper script will tag that built image with a new name
that will be used to replace the old image name. This change updates the
build-setup.sh, the qemu-build.sh, and the kubernetes-launch.sh
