    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:

Title:
  Issues booting with os_distro=centos7.0

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  If we have os_distro=centos this isn't known by os-info, so we get:

  Cannot find OS information - Reason: (No configuration information
  found for operating system centos7): OsInfoNotFound: No configuration
  information found for operating system centos7

  If we "fix" it to os_distro=centos7.0 we get:

  Instance failed to spawn: UnsupportedHardware: Requested hardware
  'virtio1.0-net' is not supported by the 'kvm' virt driver

  This is with Rocky, but was also happening with Queens, I believe.
