selftests/bpf: Fix umount cgroup2 error in test_sockmap
This patch fixes the following "umount cgroup2" error in test_sockmap.c:
(cgroup_helpers.c:353: errno: Device or resource busy) umount cgroup2
Cgroup fd cg_fd should be closed before cleanup_cgroup_environment().
Fixes: 13a5f3ffd202 ("bpf: Selftests, sockmap test prog run without setting cgroup")
