[libvirt] PATCH: Handle case of no domains in openvz driver

[Daniel P. Berrange]

If running the openvz driver on a machine with no containers currently
defined, it throws an error

  # ./src/virsh --connect openvz:///system list
  libvir: OpenVZ error : internal error Failed to parse vzlist output
   Id Name                 State
  ----------------------------------


This is because of a failure to check for the EOF condition. This patch
adds the missing check
