8268566: java/foreign/TestResourceScope.java timed out

[mcimadamore]

This patch contains another minor tweak to TestResourceScope as we have seen this test timing out at least once (on arm64).

I realized that some of the logic recently introduced in the test could lead to the test waiting forever: for instance, if all threads are executed right away before the main thread gets a chance to do anything, we'd be in a state where the lock count is zero, and no other thread will update it. I've removed the while loop - as that's not essential to make sure that the test works (what we want is to trigger a close operation that is concurrent with respect some acquire/release).

I've also lowered the number of threads - which was using 10K - that was good for stress testing, but it's not a good number in more realistic conditions.
