message: fuzz: enable optimizations in other profiles
  The problem was that the fuzzer wasn't running with optimizations, which
  means it was likely compiled in debug mode. So setting the optimization
  level on the release profile won't do any good. Instead, we set it on
  the debug and test profiles, which should cover it.
