I know what is going on. It is a race between the cleanup and setup for the rootless cni namespace. I think I know how to fix this. |

There was an race condition when calling `GetRootlessCNINetNs()`. It created the rootless cni directory before it got locked. Therefore another process could have called cleanup and removed this directory before it was used resulting in errors. The lockfile got moved into the XDG_RUNTIME_DIR directory to prevent a panic when the parent dir was removed by cleanup. Fixes containers#10930 Fixes containers#10922 To make this even more robust `GetRootlessCNINetNs()` will now return locked. This guarantees that we can run `Do()` after `GetRootlessCNINetNs()` before another process could have called `Cleanup()` in between. [NO TESTS NEEDED] CI is flaking, hopefully this will fix it.

I think this is now our number-one flake:
Once this happens, the system is forevermore broken, but further attempts give a different error:
It's a hard one to track down because once it fails, many other tests fail. I will try to follow up here after our f2f.
Podman network [It] podman network prune
Podman run networking [It] podman run check dnsname plugin
