[SPARK-9376][SQL] use a seed in RandomDataGeneratorSuite
Make this test deterministic, i.e. make sure this test can be passed no
matter how many times we run it.
The origin implementation uses a random seed and gives a chance that we may
break the null check assertion
`assert(Iterator.fill(100)(generator()).contains(null))`.
