enable x2apic by default for kvm machines

This reduce context switch with multicore guests.

Even if the host cpu don't have x2apic, it's working because qemu have an virtual x2apic implementation for guest.
We need  in-kernel irqchip support for this, which is enable for kvm guest since qemu 1.3.
(I don't enable it if nokvm param is set)
