Deflake TestRunCustomRootfs by workaround

Attempt to fix #2327 by workaround

The failure is because the nerdctl can not pull all the layers,
and the ctr can do it.

Thanks, but I don't think that is a good idea to add a dependency to ctr . IMHO we have to investigate why nerdctl do not attempt to fetch correctly layers inside the ci

Thanks @fahedouch

After investigating the issue, the root cause is here:
https://github.com/containerd/containerd/blob/main/pkg/unpack/unpacker.go#L300C14-L300C14
The layer is skipped because the snapshot can be found.

But I have no idea how to fix it now :-)

So it is no longer a cli issue.
