[Libguestfs] [PATCH v2 5/5] v2v: add test for v2v with virtio-win drivers on iso

[Roman Kagan]

For that, add autofoo machinery to generate the iso out of the fake
virtio-win drivers introduced in the previous patches, and pass the
resulting image in $VIRTIO_WIN to v2v in a new test otherwise similar to
test-v2v-windows-conversion.sh.

changes since v1:
 - moved fake-virtio-win.iso under v2v
