ci: allow CONTAINER_CMD prefixed with sudo

Allow passing:
$ CONTAINER_CMD="sudo docker" ./scripts/minikube.sh cephcsi
or
$ CONTAINER_CMD="sudo podman" ./scripts/minikube.sh cephcsi

Because the container images could list in '# sudo docker images' or
'# sudo podman images' incase if the Makefile target image-cephcsi is
run with sudo
