Nikolai Barybin 4281362a96 tests: virstoragetest: Add tests for detection of qcow2 'data_file' feature ...

Add two test images showing the use of 'data_file' and 'data_file_raw'
(although the latter is not detected by libvirt) so that we can see that
the qcow2 metadata parser and backing chain populators work correctly.

The example files were created by:

 qemu-img create  -f qcow2 -o data_file=raw,data_file_raw=true,preallocation=off datafile.qcow2 1k
 qemu-img create  -f qcow2 -o data_file=rawpreallocation=off -F qcow2 -b datafile.qcow2 qcow2datafile-datafile.qcow2

Note that 'data_file_raw' is mutually exclusive with backing images.
