tests: Add extraction_filter for tarfile

Python 3.12, and earlier via security backports now issue an
DeprecationWarning when calling tarfile.extractall without an extraction
filter set. Since the only place we've called extractall is literally
right after we've created the archive, use a fully trusted filter. This
can be replaced with a filter argument to extractall in future.
