RFR(XS): 8163243 - [TESTBUG] compiler/codecache/jmx/UsageThresholdIncreasedTest.java failed with: Failed to find sun/hotspot/WhiteBox.class

Hi,

please review small fix for 8163243 - [TESTBUG] 
compiler/codecache/jmx/UsageThresholdIncreasedTest.java failed with: 
Failed to find sun/hotspot/WhiteBox.class

Test has wrong order of "build" and "run" jtreg directives, which leads 
to test failure. This fix sets correct order.

CR: https://bugs.openjdk.java.net/browse/JDK-8163243

I've tested this fix on linux-amd64.

Thanks,
Dmitrij
