[OSSTEST PATCH 16/16] ts-guests-nbd-mirror: make it work with stretch

[Wei Liu <wei.liu2@citrix.com>]

On the server side, only add oldstyle= and port= on jessie. Stretch
doesn't support or need those anymore.  Prune check for older versions
of Debian.

On the client side, generate new style configuration file.
