vm_power_manager utilize libvirt API virDomainGetVcpuPinInfo for
retrieve domU vcpu information. This API implemented from version 0.9.3.
Suse11 SP3 32bit default libvirt version is 0.8.8, so there'll be build
error. Add judgement in sample Makefile to alarm unsupport environment.

examples/vm_power_manager/channel_manager.c: In function
‘update_pcpus_mask’:
channel_manager.c:117:3: error: implicit declaration of function
‘virDomainGetVcpuPinInfo’

Fixes: 8db653ff7889 ("vm power management application")
