Now that cmake was a breaking change for all fuzz scripts, it seems fine to bundle it with another breaking change to rename the fuzz corpora directory, as discussed and approved in https://github.com/bitcoin-core/qa-assets/issues/200:
- The word “seed” in the old name doesn’t really apply. In reality it is a collection of fuzz input seeds, as well as fuzz inputs.
- The rename will also allow in the future (when there is a need and desire) to provide a minimal set of possibly hand-crafted or otherwise non-fuzz-generated fuzz seed inputs to some fuzz targets (and possibly store them in a separate folder and validate that their format is still accurate and matches the fuzz target code).
- Finally, “corpus” is renamed to corpora, to clarify that the folder holds the fuzz inputs for several fuzz targets.
