[virt-tools-list] [virt-manager PATCH] details: don't display error if machine is missing in XML

[Pavel Hrdina]

Commint 0ddec919 updated the details page.  Now the detail page of
existing domain cannot update the 'machine' value, only prints that
value.  If we cannot get the machine from domain XML, don't pass a None,
but "Unknown" instead.  This can happen if you are connecting with
virt-manager to really old libvirt, the machine value is present in
domain XML since libvirt v0.9.5.
