[PATCH 5.10 163/171] selftests/cgroup: Fix build on older distros

[Greg Kroah-Hartman]

From: Sachin Sant <sachinp@xxxxxxxxxxxxxxxxxx>

commit c2e46f6b3e3551558d44c4dc518b9667cb0d5f8b upstream.

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.
