This is observed on the linux/ppc64le/p10 builder.

On some versions of docker, /sys/fs/cgroup is mounted read-only within an unprivileged container. The test fails with:

exec_linux_test.go:524: mkdir /sys/fs/cgroup/subcg-457236693: read-only file system

Note, on the linux-ppc64le-power10osu builder, the host is ubuntu 22.04 running under the unified cgroup hierarchy, unlike the other PPC64 builders.
