HD: Added match_hypervisor_prefix to avoid wrong results

The request
wbemain -ac Xen_HostedDependency 'http://localhost/root/virt:KVM_ComputerSystem.CreationClassName="KVM_ComputerSystem",Name="qemu1"'
returned
localhost:5988/root/virt:KVM_HostSystem.CreationClassName="KVM_HostSystem",Name="localhost.localdomain"
which is wrong, as KVM_ComputerSystem is referenced to
KVM_HostSystem via KVM_HostedDependency instead of
Xen_HostedDependency.
