[SPARK-8404][Streaming][Tests] Use thread-safe collections to make the
tests more reliable
KafkaStreamSuite, DirectKafkaStreamSuite, JavaKafkaStreamSuite and
JavaDirectKafkaStreamSuite use non-thread-safe collections to collect data in
one thread and check it in another thread. It may fail the tests.
This PR changes them to thread-safe collections.
Note: I cannot reproduce the test failures in my environment. But at least,
this PR should make the tests more reliable.
