RFR: 8235964: [TESTBUG] runtime/handshake/HandshakeWalkStackFallbackTest.java fails after JDK-8231559

[Jie Fu]

Hi all,

May I get reviews for the one-line fix?
The failure was caused by an Unrecognized VM option 'ThreadLocalHandshakes'.

JBS:    https://bugs.openjdk.java.net/browse/JDK-8235964
Webrev: http://cr.openjdk.java.net/~jiefu/8235964/webrev.00/

Thanks a lot.
Best regards,
