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

[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.
