xenserver: Add script refresh-xs-network-uuids.

On pool join, the bridge.<bridge>.xs-network-uuids key is not updated
properly for the primary management interface.  We don't have a proper
fix for this problem yet, and probably won't ever have one for XenServer
5.5.0, so this commit adds a script that works around the problem.
Running the script is a shortcut for rebooting the XenServer host,
which should also solve the problem.

Bug #2097.
