Subject: [PATCH] qemu-kvm: Fix default machine options

qemu-kvm-specific machine defaults were missing for pc-0.15 to pc-1.1.
Then Daniel noted that --disable-kvm caused problems as the generated
binaries would be unable to run. As we are at it, we can drop the
kernel_irqchip=on that is now enable by default in upstream.
