In test/TestCommon.gmk the jtreg invocation will unconditionally produce an archive bundle, a zip file consisting of all the output from jtreg. When testing in JPRT, JPRT sets JPRT_ARCHIVE_BUNDLE to override the name of this zip. In all other situation, I can't see the point of creating it. It just adds unnecessary test execution time as well as bloating up the test results dir when we now save it using different means.

I propose to stop producing any zip file unless either ARCHIVE_BUNDLE or JPRT_ARCHIVE_BUNDLE is set by the user. This will make the logic continue working in JPRT.
