RFR: (XS): JDK-8213457: serviceability/sa/ClhsdbInspect.java time out

[Jini George]

Hello!

Requesting reviews for a small fix for fixing the timeout failures of 
the test: ClhsdbInspect.java by increasing the timeout value.

BugID: https://bugs.openjdk.java.net/browse/JDK-8213457
Webrev: http://cr.openjdk.java.net/~jgeorge/8213457/webrev.00/index.html

The fix has been tested with about 200 repeated runs on windows post 
this fix. The timeout was not observed.

Thanks,
Jini.
