CI `run-tests (8)` sometimes times out after 6 hours

From the CI run below, it might be that the JDK8 test runs has issues when the tasks :iceberg-hive3:test and :iceberg-mr:test run in parallel. Only JDK8 Gradle runs do include :iceberg-hive3, which explains why only the JDK8 CI test runs are affected (seen only the JDK8 test runs timing out).

I don’t know about the inner workings of both project tests, but I suspect those two projects somehow interfere with each other.

If it’s just those two test tasks, it might help to add a mustRunAfter(':iceberg-mr:test') to :iceberg-hive3:test.

Aha! So it seems that this commit fixed it. I’ll setup a PR with just that change.
