Keep consistent report with x86 for ppc platform.

1.Remove irq_injs and rpkt_per_irq since it's not supported any
more in kvm state

2.Since powerpc doest not support io_exits in kvm state, uses exits
for all platform.

3.Fail to control last numa node by numactl tool in some ppc machine,
so switch to node 0 instead.
