[SPARK-17003][BUILD][BRANCH-1.6] release-build.sh is missing hive-thriftserver for scala 2.11

## What changes were proposed in this pull request?
hive-thriftserver works with Scala 2.11 (https://issues.apache.org/jira/browse/SPARK-8013). So, let's publish scala 2.11 artifacts with the flag of `-Phive-thfitserver`. I am also fixing the doc.
