The fuzz test cases now print the original test paths during execution.
This exploits this extra information and reports a hash of only one
original source file from the section that caused a difference.
The hash size is now limited to 3 to avoid possible duplicate
explosion, in case this doesn't work out as expected.
This prepares for patch 3 of:

Reason for revert:
Setting the BAD_BUILDS_CHECK env variable should
be enough. Lets revert this as the code doesn't
look particularly good. There must be another
problem still that needs investigation.

This adds the correctness fuzzer harness files to the output
directory guarded by a gn arg.
The switch will be turned on on the builder uploading builds to
clusterfuzz.

This makes sure the metadata is found during minimization. Also renames
the test files to fit the naming pattern.

Initial version of the correctness fuzzer harness for manual testing
and experiments.
For automated usage, some outstanding TODOs are left in the code. E.g.
- Hash source file names in error case
- Bundle script in out directory with executables
- Some suppressions are tied to already fixed bugs. We'll keep it like that for now to test
removing those suppressions in production later.
