[PATCH v2 4/9] test: move fitimage testdata generation to fixture and drop script

[Jonas Rebmann <jre@pengutronix.de>]

Get rid of scripts/generate_testfs.sh and the logic around it. Test data
generation should happen within pytest.

Move test data (its config for fitimages) from .github/testfs to
test/testdata for good measure.
