RFR: 8259446: runtime/jni/checked/TestCheckedReleaseArrayElements.java fails with stderr not empty [v2]

[David Holmes]

> The test checks stderr is empty.
> The test is run in our tier3 CI testing.
> Tier3 (and some other tiers) has a configuration that includes the -showversion flag which outputs the version string to stderr.
> 
> => ergo the test fails because stderr is not empty!
> 
> Fix: exec the secondary VM without including the jtreg test VM arguments.
> 
> I think this is really a bug in our test job definitions and we've been very lucky to not encounter problems with using `-showversion`, but as a quick fix this suffices, and we don't expect any other JVM flags to have any impact here.
> 
> Tested by running jtreg with/without -showversion being passed to JVM under test.
> Tier3 test run in progress too.
> Thanks.
