HDDS-2185. createmrenv failure not reflected in acceptance test result

[adoroszlai]

What changes were proposed in this pull request?

Avoid purging results dir when testlib.sh is sourced. Explicitly do that during docker env startup.

https://issues.apache.org/jira/browse/HDDS-2185

How was this patch tested?

Ran ozone-mr/hadoop31 test, verified that robot-hadoop31-hadoop31-createmrenv-scm.xml is present along with other results.

Note that with this change, acceptance tests are expected to be failing. They should have been failing with HDDS-2187 since HDDS-2101 was merged. They are being fixed in #1537.
