On older distros struct clone_args does not have a cgroup member,
leading to build errors:
cgroup_util.c: In function 'clone_into_cgroup':
cgroup_util.c:343:4: error: 'struct clone_args' has no member named 'cgroup'
cgroup_util.c:346:33: error: invalid application of 'sizeof' to incomplete
type 'struct clone_args'
But the selftests already have a locally defined version of the
structure which is up to date, called __clone_args.
So use __clone_args which fixes the error.

V2: Replace all instances of clone_args by __clone_args

Not sure how you generated the patch. I had to use git am -p2
Applied to linux-kselftest next - please make sure to generate from
top level.
