selftests/bpf: Remove kmem subtest from cgroup_iter_memcg

Browse source

When cgroup.memory=nokmem is set in the kernel command line, kmem
accounting is disabled. This causes the test_kmem subtest in
cgroup_iter_memcg to fail because it expects non-zero kmem values.

Remove the kmem subtest altogether since the remaining subtests
(shmem, file, pgfault) already provide sufficient coverage for
the cgroup iter memcg functionality.
