Allow users to generate a kubernetes yaml off non running containers

Currently if you attempt to create a kube.yaml file off of a non running
container where the container runs as a specific User, the creation
fails because the storage container is not mounted. Podman is supposed to
read the /etc/passwd entry inside of the container but since the
container is not mounted, the c.State.Mountpoint == "".  Podman
incorrectly attempts to read /etc/passwd on the host, and fails if the
specified user is not in the hosts /etc/passwd.

This PR mounts the storage container, if it was not mounted so the read
succeeds.
