Fix flake in upgrade tests
The cni plugins need access to /run/cni and the dnsname plugin needs
access to /run/containers.
The race condition was basically that a `podman stop` could either do the
cleanup itself or the spawned cleanup process would do the cleanup if it
was fast enough. The `podman stop` is executed on the host while the
podman cleanup process is executed in the "parent container". The parent
container contains older plugins than on the host. The dnsname plugin
before version 1.3 could error and this would prevent CNI from
doing a proper cleanup. The plugin errors because it could not find its
files in /run/containers. On my system the test always failed because
the cleanup process was always faster than the stop process. However in
the CI VMs the stop process was usually faster and so it failed only
sometimes.
Fixes #11558
