    Stop sending bad values from libosinfo to libvirt

    When we try to use either virtio1.0-block or virtio1.0-net it is
    correctly rejected by libvirt. We get these returned from libosinfo for
    newer operating systems that support virtio1.0.

    As we want to support libvirts older than 5.2.0, its best we just request
    "virtio", please see:
    https://libvirt.org/formatdomain.html#elementsVirtioTransitional

    You can see virtio1.0-net and virtio-block being added here:
