Add generic support for SOCKET_URING_OP_SETSOCKOPT, expanding the
current case, that just execute if level is SOL_SOCKET.
This implementation basically calls sock->ops->setsockopt() with a
kernel allocated optval;
Since the callback for ops->setsockopt() is already using sockptr_t,
then the callbacks are leveraged to be called directly, similarly to
__sys_setsockopt().
