RFR: 8351382: New test containers/docker/TestMemoryWithSubgroups.java is failing [v4]

[Sergey Chernyshev]

> The new test fails in rootless Docker mode after [JDK-8343191](https://bugs.openjdk.org/browse/JDK-8343191):
> 
> containers/docker/TestMemoryWithSubgroups.java
> 
> [STDERR]
> 
> Resource limits are not supported and ignored on cgroups V1 rootless systems
> 
> [STDOUT]
> 
> mkdir: cannot create directory '/sys/fs/cgroup/memory/test': Permission denied
> sh: /sys/fs/cgroup/memory/test/memory.limit_in_bytes: No such file or directory
> sh: /sys/fs/cgroup/memory/test/cgroup.procs: No such file or directory
> 
> The test TestMemoryWithSubgroups.java uses `--privileged` mode to modify process' cgroup, that has no effect in rootless mode. The test has to be skiped.
> 
> The fix is to query `info -f {{println .SecurityOptions}}` and check whether it has `name=rootless` in the output.
