iotests: Make 150 use qemu-img map instead of du
The actual on-disk size of a file does not only depend on factors qemu can control. Thus, we should not depend on this to determine whether a file has indeed been fully allocated. Instead, use qemu-img map and hope that if an area is referenced, it is indeed allocated, too. Also, limit the supported image formats to raw and qcow2 because the actual qemu-img map output may depend on the image format.
