Skip the unpacking of the QEMU image

[pothos]

We now provide the qcow2 image with inline compression. This means we can skip the unpacking. This is available from Stable 3602.2.0 and the hands-on 4 tutorial was updated to this version - hence we should wait for 3602.2.1 to be out before merging this change.
