[SPARK-5700] [SQL] [Build] Bumps jets3t to 0.9.3 for hadoop-2.3 and hadoop-2.4 profiles

This is a follow-up PR for #4454 and #4484. JetS3t 0.9.2 contains a log4j.properties file inside the artifact and breaks our tests (see SPARK-5696). This is fixed in 0.9.3.

This PR also reverts hotfix changes introduced in #4484. The reason is that asking users to configure HiveThriftServer2 logging configurations in hive-log4j.properties can be unintuitive.
