tools: xend: tolerate empty state/*.xml
Bugzilla 1680: Xend fails to start if /var/lib/xend/state/*.xml are empty
which I get often when replacing the Xen hypervisor with a newer version.
This can be easily be reproduced under Fedora Core 16 by installing
xen RPMs and then replacing the xen.gz with a newer version.
