[SPARK-27592][SQL] Set the bucketed data source table SerDe correctly

## What changes were proposed in this pull request?

Hive using incorrect **InputFormat**(`org.apache.hadoop.mapred.SequenceFileInputFormat`) to read Spark's **Parquet** bucketed data source table.
Spark side:
```sql
spark-sql> CREATE TABLE t (c1 INT, c2 INT) USING parquet CLUSTERED BY (c1) SORTED BY (c1) INTO 2 BUCKETS;
2019-04-29 17:52:05 WARN  HiveExternalCatalog:66 - Persisting bucketed data source table `default`.`t` into Hive metastore in Spark SQL specific format, which is NOT compatible with Hive.
spark-sql> DESC FORMATTED t;
c1	int	NULL
c2	int	NULL

So it's non-bucketed table at Hive side. This pr set the `SerDe` correctly so Hive can read these tables.
