Add support for getsockopt command (SOCKET_URING_OP_GETSOCKOPT), where
level is SOL_SOCKET. This is leveraging the sockptr_t infrastructure,
where a sockptr_t is either userspace or kernel space, and handled as
such.

Function io_uring_cmd_getsockopt() is inspired by __sys_getsockopt().

We probably need to also have bpf bits in the new
io_uring_cmd_getsockopt?

It might be interesting to have the BPF hook for this function as
well, but I would like to do it in a following patch, so, I can
experiment with it better, if that is OK.
