Parameterize DBBasicTest.CompactBetweenSnapshots (#7301)

Summary:
DBBasicTest.CompactBetweenSnapshots can time-out in some slow-I/O hosts. Parameterize it so that single test runs shorter.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7301

Test Plan: Run the test and see see different runs are of different configerations in a hacky way.
