bpf: Disallow bpf_{g,s}etsockopt() in cgroup UNIX getname hooks

In the Linux kernel, the following vulnerability has been resolved:

bpf: Disallow bpf_{g,s}etsockopt() in cgroup UNIX getname hooks

_bpf_setsockopt() and _bpf_getsockopt() call sock_owned_by_me() for
full sockets, so these helpers expect the socket lock to be held.

BPF_CGROUP_UNIX_GETPEERNAME and BPF_CGROUP_UNIX_GETSOCKNAME run BPF
programs without acquiring the socket lock. A program attached to
either hook can therefore trigger the sock_owned_by_me() warning by
calling bpf_setsockopt() or bpf_getsockopt().

Disallow bpf_setsockopt() and bpf_getsockopt() for CGROUP_UNIX_GETPEERNAME
and CGROUP_UNIX_GETSOCKNAME.
