RFR: 8361754: New test runtime/jni/checked/TestCharArrayReleasing.java can cause disk full errors

[David Holmes]

Please review this trivial fix to the test, which needed to set `-XX:-CreateCoredumpsOnCrash`, after which the exit code is 1 on all platforms.

The test now runs a lot faster too.

Thanks
