Code review comment for ~paelzer/uvtool:fix-libvirt-dependency

Hi Robie,
I see where you are heading to in regard to the backports, and I think something like that is ok - as it will allow us to drop libvirt-bin some day.
But the split is different as libvirt-bin split into libvirt-daemon, libvirt-daemon-system and libvirt-clients.

I think it then should look like:
Depends: libvirt-daemon-system, libvirt-clients | libvirt-bin
Which is: new | old
