[SPARK-1429] Spark shell fails to start after "sbt clean assemble-deps package"

JIRA issue: [SPARK-1429](https://issues.apache.org/jira/browse/SPARK-1429)

Spark shell fails to start after `sbt clean assemble-deps package`. A `*` should be added in `compute-classpath.sh` line 55 to make sure both `spark-assembly-xxx-deps.jar` and `spark-hive-assembly-xxx-deps.jar` are taken into account.
