If ``preparer.require_hashes`` is True, don't use the wheel cache,
because cached wheels, always built locally, have different hashes
than the files downloaded from the index server and thus throw false
hash mismatches. Furthermore, cached wheels at present have
nondeterministic contents due to file modification times.
