MXS-1738 Copy AF_UNIX data from listener to client dcb

Browse Source 
We need to copy some data from a AF_UNIX based listener dcb
to the accepted client dcb, to prevent assertion violation in
dcb_get_port(). Further, to be able to log the path in the case
of an authentication error we need to copy that as well.
