func EvacuateCgroup2(evac string) error

EvacuateCgroup2 evacuates cgroup2. Must be called in the parent PID namespace.

When the current process belongs to "/foo" group (visible under "/sys/fs/cgroup/foo") and evac is like "bar", - All processes in the "/foo" group are moved to "/foo/bar" group, by writing PIDs into "/sys/fs/cgroup/foo/bar/cgroup.procs" - As many controllers as possible are enabled for "/foo/*" groups, by writing "/sys/fs/cgroup/foo/cgroup.subtree_control"

Returns nil when cgroup2 is not enabled. Ported from https://github.com/rootless-containers/usernetes/commit/46ad812db7489914897ff8b1774f2fab0efda62b
