launch: libvirt: Create qcow2 overlays for read-only drives and the appliance.
Instead of adding the snapshot=on option via <qemu:arg>, create qcow2
overlays for any read-only drives and the appliance using 'qemu-img
create' + a temporary file.
This is a workaround for missing support for <transient/> in libvirt's
qemu driver. Also for the unpredictable way that libvirtd handles
$TMPDIR: we want to control where the temporary disk is created.
Currently it is also much slower, because qemu-img is slow. However
we hope to fix qemu upstream.
