[Libguestfs] [PATCH v3 6/6] v2v: ova: don't extract files from OVA if it's not needed

We don't have to always extract all files from the OVA archive. The OVA, as defined in the standard, is plain tar. We can work directly over the tar archive if we use correct 'offset' and 'size' options when defining the backing file for QEMU. This puts much lower requirement on available disk space. Since the virt-v2v behaviour for OVA input now depends on QEMU version available this affects some of the tests. The affected tests will have two *.expect files and the expected result also has to depend on the QEMU used.
