This test depends on TarFile.addfile() to add tar member header without
writing the member data, which we write ourself using qemu-nbd. Python
3.13 changed the function in a backward incompatible way[1] to require a
file object for tarinfo with non-zero size, breaking the test:
-[{"name": "vm.ovf", "offset": 512, "size": 6}, {"name": "disk", "offset": 1536, "size": 393216}]
+Traceback (most recent call last):
+ File "/home/stefanha/qemu/tests/qemu-iotests/302", line 118, in <module>
+ tar.addfile(disk)
+ ~~~~~~~~~~~^^^^^^
+ File "/usr/lib64/python3.13/tarfile.py", line 2262, in addfile
+ raise ValueError("fileobj not provided for non zero-size regular file")
+ValueError: fileobj not provided for non zero-size regular file
The new behavior makes sense for most users, but breaks our unusual
usage. Fix the test to add the member header directly using public but
undocumented attributes. This is more fragile but the test works again.
This also fixes a bug in the previous code - when calling addfile()
without a fileobject, tar.offset points to the start of the member data
instead of the end.

Instead of qemu_img_log("info", ..) use generic helper img_info_log().
img_info_log() has smarter logic. For example it use filter_img_info()
to filter output, which in turns filter a compression type. So it will
help us in future when we implement a possibility to use zstd
compression by default (with help of some runtime config file or maybe
build option). For now to test you should recompile qemu with a small
addition into block/qcow2.c before
"if (qcow2_opts->has_compression_type":
if (!qcow2_opts->has_compression_type && version >= 3) {
qcow2_opts->has_compression_type = true;
qcow2_opts->compression_type = QCOW2_COMPRESSION_TYPE_ZSTD;
}

We are going to drop group file. Define group in tests as a preparatory
step.
The patch is generated by
cd tests/qemu-iotests
grep '^[0-9]\{3\} ' group | while read line; do
file=$(awk '{print $1}' <<< "$line");
groups=$(sed -e 's/^... //' <<< "$line");
awk "NR==2{print \"# group: $groups\"}1" $file > tmp;
cat tmp > $file;
done

Add test for "qemu-img convert -O qcow2 -c" to NBD target. The tests
create a OVA file and write compressed qcow2 disk content directly into
the OVA file via qemu-nbd.
