Our commit e13e8808 was way too generic. Currently, virtlogd is
used only for chardevs type of file and nothing else. True, we
must not relabel the path in this case, but we have to in all
other cases. For instance, if you want to have a physical console
attached to your guest:

    <console type='dev'>
      <source path='/dev/ttyS0'/>
      <target type='virtio' port='1'/>
    </console>

Starting such domain fails because qemu doesn't have access to
/dev/ttyS0 because we haven't relabelled the path.
