[SPARK-14201][SQL] handle empty file for new data source strategy

It's possible that users will write empty files to data dir. For example,
write data to JSON data source with one line string, and default parallelism is
2, we will write an empty file and a file with all data. The new data source
should be able to handle it.

new tests in `FileSourceStrategySuite`
