RFR: 8267651: runtime/handshake/HandshakeTimeoutTest.java times out when dumping core

[David Holmes]

Please review this trivial test fix to add -XX:-CreateCoredumpOnCrash to the exec'd VM that we expect to crash with SIGILL. If the core dump is generated it can take a long time on macos and cause the whole test to timeout.

Testing: ran 50x on macos-x64, plus local linux-x64

Thanks,
David
