cleanup: add new --stopped-only option

The podman container cleanup process runs asynchronous and by the time
it gets the lock it is possible another podman process already did the
cleanup and then did a new init() to start it again. If the cleanup
process gets the lock there it will cause very weird things.

This can be observed in the remote start API as CI flakes.

Fixes #23754
