[C++] S3 stress tests can fail to delete a temporary directory

### Describe the enhancement requested

This seems to be causing spurious failures of the stress test, [for example](https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/builds/48073408#L3424):

```
API: DeleteMultipleObjects(bucket=stress, multiObject=true, numberOfObjects=1000)

```

I'm not sure this is actually the issue; [other tests](https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/builds/48073408#L3473) can still pass even if deletion of a temporary directory succeeds:

```
