when running with uid 0 (like in nested container), podman run fails
sporadically with:
``
Error: preparing container ... for attach: container uses ID mappings ([]specs
.LinuxIDMapping{specs.LinuxIDMapping{ContainerID:0x3e9, HostID:0x0,
Size:0x1}}), but doesn't map UID 0
```
Since default user in containers is 0 (run without -u option), there is
no need to repeat that in this case.
