[Libvir] [PATCH] Fix Xen-3.2 hypercalls

While testing against Xen-3.2 I found out that the Xen hypercalls failed, this patches fixes it by checking the newer sysctl versions when initializing the driver. I also merged the associated debugging with the DEBUG from libvirt.c, to allow easier debugging of this issue.
