Subject: [PATCH] Try to fix DBSSTTest.RateLimitedDelete flakiness (#4840)

Summary:
DBSSTTest.RateLimitedDelete is flakey. The root cause is not completely identified, but
the compaction waiting in the test doesn't strictly wait for compaction cleaning to finish, which
may cause test flakiness. Fix it first and see whether the failures still happen.
