[SPARK-8567] [SQL] Increase the timeout of o.a.s.sql.hive.HiveSparkSubmitSuite to 5 minutes.

https://issues.apache.org/jira/browse/SPARK-8567

Looks like "SPARK-8368: includes jars passed in through --jars" is pretty flaky now. Based on some history runs, the time spent on a successful run may be from 1.5 minutes to almost 3 minutes. Let's try to increase the timeout and see if we can fix this test.
