selftests/bpf: Add tests for bpf_cgroup_read_xattr
Add tests for different scenarios with bpf_cgroup_read_xattr:
1. Read cgroup xattr from bpf_cgroup_from_id;
2. Read cgroup xattr from bpf_cgroup_ancestor;
3. Read cgroup xattr from css_iter;
4. Use bpf_cgroup_read_xattr in LSM hook security_socket_connect.
5. Use bpf_cgroup_read_xattr in cgroup program.
