Remove 1000 element arrays from tests.

This removes the arrays of size 1000 from the set of test data for
stream tests.

On lower-power Android devices these tests often run for a very long
time and sometimes even time out or fail with out of memory errors.

At the same time this specific size didn't reveal any errors that
weren't also revealed at smaller sizes.

For example, org.openjdk.tests.java.util.stream.ExplodeOpTest goes from
running for 34:03 minutes to 3:42 minutes on a bullhead device.
