Cache generated binary across jobs

- retrieved by the commit hash
- removes bindata tags from integration tests, because it does not seem
  to be required
- due to the missing automatically generated data, the zstd tests fail
  (they use repo data including node_modules (!) as input to the test,
  there is no apparent reason for the size constants)
