[hotfix][s3] fix HadoopS3FileSystemITCase leaving test directories behind
in S3
## What is the purpose of the change
This PR fixes `HadoopS3FileSystemITCase` leaving a test directory behind
since it always created a random test (base) directory in S3 which was never
cleaned up.
Please note, that the individual tests create sub-directories and also
always delete those.
## Brief change log
- if S3 tests are run, add a cleanup that removes the created test directory
- make sure that the test does not operate on an existing directory so that
we do not accidentally remove something we shouldn't
## Verifying this change
This change modifies tests and can be verified as follows:
- manually checked the created test directory is deleted from S3
