[SendaoYan]

> Hi all,
> 
> Test containers/docker/TestMemoryWithSubgroups.java fails on some docker images. If the default user inside docker is non root user, test will report fails "mkdir: cannot create directory '/sys/fs/cgroup/memory': Permission denied". This PR add docker run parameter `--user root` to force use root user inside docker containter.
> 
> Change has been verified locally on ubuntu22(cgroup v2). Test-fix only, no risk.
