IMPALA-6318: Adjustment for hanging query cancellation test

Apparently test_query_cancellation_during_fetch hangs occasionally
in Jenkins builds. The Impala debug page shows the query being
cancelled, however, on the host the ImpalaShell process related to
that query is still running.

Since I had no luck in reproducing the issue locally I only have a
theory what might be going on here: The query is cancelled
successfully on Impala backend and when the test tries to get the
stdout and stderr from the ImpalaShell it gets stuck. It might be
the case that the thread fetching the query results holds the
stdout, so as a workaround there is a new option for
util/ImpalaShell to omit the stdout because this test wouldn't use
it anyway.
