examples/vm_power_manager: fix build with libvirt < 1.0

Browse Source 
virNodeGetCPUMap introduced in libvirt 1.0. In some linux distributions
like Ubuntu12/14 and Fedora18, libvirt version is older than 1.0. So this
sample will not build pass.

Replace "virNodeGetCPUMap" with another libvirt API "virNodeGetInfo".
