qemux86-64: Support for KVM, paravirt and virtio added

    KVM, paravirtualization and virtio drivers are now activated
    in runqemu using the kvm option flag for qemux86-64.
    Host CPU features are also exported to guest OS (Yocto Linux).
    Usage example: runqemu qemux86-64 core-image-x11 kvm

    Implements [YOCTO #2550].
