bpf, sk_msg: Add some generic helpers that may be useful from sk_msg
Add these generic helpers that may be useful to use from sk_msg programs.
The helpers do not depend on ctx so we can simply add them here,
BPF_FUNC_perf_event_output
BPF_FUNC_get_current_uid_gid
BPF_FUNC_get_current_pid_tgid
BPF_FUNC_get_current_cgroup_id
BPF_FUNC_get_current_ancestor_cgroup_id
BPF_FUNC_get_cgroup_classid
