IMPALA-3367: Ensure runtime filters tests run on 3 nodes

Runtime filter tests require that each scan gets assigned to three
backends. In our test environment (with Impala daemons on the same
machine) concurrent load can cause these scans to get assigned to only
two nodes, which breaks the runtime filter tests. See IMPALA-2479 for
more details.

This patch changes the tests to run sequentially.
