xenserver: Set internal network-uuids in Bridge table on XS5.5

On XenServer 5.5, interface-reconfigure is not called when creating
internal bridges, so we jump through extra hoops to determine the
network UUIDs.  The code that handled this was not properly retrieving
the UUIDs from XAPI, so the field would never be set.  This commit
corrects that.

Bug #2666
