These lines were ignored by flynt in previous scripted-diffs because of the multiline nature.
I manually edited these lines to put them on a single line, ran flynt again, then manually formatted the resulting string.
There are more of these lines in test_runner.py, in test_framework/*.py files, in src/test/fuzz/test_runner.py and in test/util/bitcoin-util-test.py. These will be addressed in a follow-up to avoid making this diff even larger.
Depends on D13202
