conntrackd: cthelper: add QueueLen option

This patch adds the QueueLen option, that allows you to increase
the maximum number of packets waiting in the nfnetlink_queue to
receive a verdict from userspace.

Rising the default value (1024) is useful to avoid hitting the following
error message: "nf_queue: full at X entries, dropping packets(s)".
