bpf: Use cgroup_{common,current}_func_proto in more hooks
The following hooks are per-cgroup hooks but they are not
using cgroup_{common,current}_func_proto, fix it:
* BPF_PROG_TYPE_CGROUP_SKB (cg_skb)
* BPF_PROG_TYPE_CGROUP_SOCK_ADDR (cg_sock_addr)
* BPF_PROG_TYPE_CGROUP_SOCK (cg_sock)
* BPF_PROG_TYPE_LSM+BPF_LSM_CGROUP
Also:
* move common func_proto's into cgroup func_proto handlers
* make sure bpf_{g,s}et_retval are not accessible from recvmsg,
getpeername and getsockname (return/errno is ignored in these
places)
* as a side effect, expose get_current_pid_tgid, get_current_comm_proto,
get_current_ancestor_cgroup_id, get_cgroup_classid to more cgroup
hooks
