[SPARK-14436][SQL] Make JavaDatasetAggregatorSuiteBase public.

Without this, unit tests that extend that class fail for me locally
on maven, because JUnit tries to run methods in that class and gets
an IllegalAccessError.

Author: Marcelo Vanzin <vanzin@cloudera.com>

Closes #12212 from vanzin/SPARK-14436.
