sdong b1a53db327 FaultInjectionTestFS::DeleteFilesCreatedAfterLastDirSync() to recover… (#8501) 
Summary:
… small overwritten files.
If a file is overwritten with renamed and the parent path is not synced, FaultInjectionTestFS::DeleteFilesCreatedAfterLastDirSync() will delete the file. However, RocksDB relies on file renaming to be atomic no matter whether the parent directory is synced or not, and the current behavior breaks the assumption and caused some false positive: https://github.com/facebook/rocksdb/pull/8489

Since the atomic renaming is used in CURRENT files, to fix the problem, in FaultInjectionTestFS::DeleteFilesCreatedAfterLastDirSync(), we recover the state of overwritten file if the file is small.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/8501

Test Plan: Run stress test for a while and see it doesn't break.
