    libvirt: Get the CPU model, not 'arch' from get_capabilities()
    
    This fixes a regression introduced with change
    Ib37ff6fc2e1f9de0e60adca54e87c74f45f12ffa.
    
    Without this, setting [libvirt]/cpu_model_extra_flags
    to some value results in libvirt failing to start with
    an error like this:
    
      Configured extra flag: aes it not correct, or the host CPU
      does not support this flag. Please correct the config and
      try again. Migration pre-check error: CPU doesn't have
      compatibility.
