env_test */RunMany/* tests to run individually (#6931)

Summary:
When run */RunMany/* tests individually, e.g. ChrootEnvWithDirectIO/EnvPosixTestWithParam.RunMany/0, they hang. It's because they insert to background thread pool without initializing them. Fix it.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6931

Test Plan: Run ChrootEnvWithDirectIO/EnvPosixTestWithParam.RunMany/0 by itself and see it passes.
