Use `java` instead of `sbt` to run SharkServer2

Otherwise CLASSPATH settings computed by the `run` script is ignored. A direct consequence is that `hive-site.xml` and Hadoop configurations can't be properly loaded.

Shark .class files are moved to the front of Hive jar files in CLASSPATH so that classes like HiveServer2 hacked in Shark can be found before their corresponding genuine Hive version.
