[SPARK-16515][SQL]set default record reader and writer for script
transformation
## What changes were proposed in this pull request?
In ScriptInputOutputSchema, we read default RecordReader and RecordWriter
from conf. Since Spark 2.0 has deleted those config keys from hive conf, we
have to set default reader/writer class name by ourselves. Otherwise we will
get None for LazySimpleSerde, the data written would not be able to read by
script. The test case added worked fine with previous version of Spark, but
would fail now.
## How was this patch tested?
added a test case in SQLQuerySuite.
Closes #14169
