db_basic_bench fix for DB object cleanup (#9939)

Browse Source 
Summary:
Use `unique_ptr<DB>` to make sure the DB object is deleted. Previously it was not, which led to accumulating file descriptors for deleted directories because a `DBImpl::db_dir_` from each test remained alive.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9939

Test Plan: run `lsof -p $(pidof db_basic_bench)` while benchmark runs; verify no FDs for deleted directories.
