Transparent mode in a multi-stage chain will fail after the first step
...
because the (ip,port) is already bound. With this change, the bind is
retried with a different port to at least keep the same IP address, which
for most uses is all that is needed. I've tested this on my own system
where sslh is used downstream from stunnel, with both in transparent mode.
