[SPARK-17213][SQL][FOLLOWUP] Re-enable Parquet filter tests for binary and string

## What changes were proposed in this pull request?

This PR proposes to enable the tests for Parquet filter pushdown with binary and string.

This was disabled in https://github.com/apache/spark/pull/16106 due to Parquet's issue but it is now revived in https://github.com/apache/spark/pull/16791 after upgrading Parquet to 1.8.2.

## How was this patch tested?

Manually tested `ParquetFilterSuite` via IDE.
