This bug was introduced in https://github.com/containers/podman/pull/8906.
When we use 'podman rm/restart/stop/kill etc...' command to
the container running with --rm, the OCI runtime directory
remains at /run/<runtime name> (root user) or
/run/user/<user id>/<runtime name> (rootless user).
This bug could cause other bugs.
For example, when we checkpoint the container running with
--rm (podman checkpoint --export) and restore it
(podman restore --import) with crun, error message
"Error: OCI runtime error: crun: container `<container id>`
already exists" is outputted.
This error is caused by an attempt to restore the container with
the same container ID as the remaining OCI runtime's container ID.
Therefore, I fix that the cleanupRuntime() function runs to
remove the OCI runtime directory,
even if the container has already been removed by --rm option.
