Subject: [PATCH] Fix crash test allocation error under TSAN

Summary:
We were seeing the following error: "ThreadSanitizer: DenseSlabAllocator overflow. Dying."

It is fixable by mmap'ing a smaller region for keys' expected values, which this PR achieves by reducing the number of keys.
Closes https://github.com/facebook/rocksdb/pull/3803
