[SPARK-25964][SQL][Minor] Revise OrcReadBenchmark/DataSourceReadBenchmark
case names and execution instructions

1. OrcReadBenchmark is under hive module, so the way to run it should be
```
build/sbt "hive/test:runMain <this class>"
```
2. The benchmark "String with Nulls Scan" should be with case "String with
Nulls Scan(5%/50%/95%)", not "(0.05%/0.5%/0.95%)"
3. Add the null value percentages in the test case names of
DataSourceReadBenchmark, for the benchmark "String with Nulls Scan" .
