IMPALA-4335: Don't send 0-row batches to sink

This patchr restores some behaviour from pre-IMPALA-2905 where the
PlanFragmentExecutor would not send 0-row batches to the sink. Although
0-row batches are legal, they're not very useful for clients to
receive (and clients may not correctly process them).

No query was found which reliably produced 0-row batches, so no test is
added.
