reduce memory usage in CircleCI mini crashtest (#10639) 

Summary:
Example flake where CircleCI reports memory at 99% and process gets killed with signal 9 (likely OOM): https://app.circleci.com/pipelines/github/facebook/rocksdb/18085/workflows/bdadbfe6-c40f-4ccb-a5db-fc8c4036f20a/jobs/475628

The previous settings of max_key=25000000, column_families=10, and log2_keys_per_lock=2 resulted in 3GB memory usage just for SharedState. The locks alone consume at least (25000000 keys per CF) * (10 CFs) / (2^2 keys per lock) * (40 bytes per lock) = 2.3GB. This PR reduces it 10x by reducing max_key by that factor.
