sandbox: Stop and clean up containers that fail to create

A container that is created and added to a sandbox can still fail
the final creation steps. In this case, the container must be stopped
and have its resources cleaned up to prevent leaking sandbox mounts.

Forward port of https://github.com/kata-containers/runtime/pull/2826

Fixes #2816
