The first patch enable support for use kvm without vhost a new option (kvm-vhost)
was added for use kvm with vhost,

The second and third patch enables usage of virtio devices/drivers in qemu machines
by default, I ran all oe-core qemu machines with core-image-minimal, i tested 
arm, arm64, arm-lsb, x86, x86-64, x86-64-lsb running sanity tests and x86 with
core-image-rt.

The following changes since commit 8578bc17b54da97d42b257b3c8f398ac52b91a9f:

  libc-package: Fix localedef multilib dependency issues (2015-10-20 10:12:01 +0100)

KVM can be used without vhost so add a new option to runqemu for
use kvm with vhost.

Example,
	runqemu qemux86 core-image-minimal kvm # kvm without vhost
	runqemu qemux86 core-image-minimal kvm-vhost # kvm with vhost

Enable virtio usage for default in runqemu also get rid
of duplicate configuration from now all qemu machines uses
virtio.
