db_bench -use_stderr_info_logger to print timestamp (#10435) 

Summary:
Right now db_bench -use_stderr_info_logger would redirect RocksDB info logging to stderr but no timetamp is printed out. Add timestamp to there.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/10435

Test Plan: Run "db_bench -use_stderr_info_logger"
