remove fingerprints/fingerprints.yaml (#3474)

* remove fingerprints/fingerprints.yaml

No idea what this file is, but it's annoying because
we have to skip it in many scripts because it does not
contain regular rules and target test files.
Let's just remove it to simplify things.

test plan:
wait for green CI checks

* remove every use of fingerprints (each time it was to skip the dir)
