RFR: 8261340: Fix 'deprecated' warnings in the vmTestbase/nsk tests

[Harold Seigel]

Please review this small fix for JDK-8261340 to clean up deprecation warnings, such as the following, in the vmTestbase/nsk tests.

    warning: [dep-ann] deprecated item is not annotated with @Deprecated

The change was tested by running the tests locally and checking for the warnings.  It was regression tested with tiers 1-2 on Linux, Mac OS, and Windows and tiers 3-5 on Linux x64.

Thanks, Harold
