Subject: [PATCH bpf-next 2/2] selftests/bpf: Fix test that uses cgroup_iter order

Previous commit added a CGROUP prefix to the bpf_cgroup_iter_order.
It fixes the commit that introduced cgroup iter. This commit fixes
the selftest that uses the cgroup_iter_order. Because they fix two
different commits, so put them in separate patches.

Fixes: 88886309d2e8 ("selftests/bpf: add a selftest for cgroup hierarchical stats collection")
