RFR: 8166460: jdk/internal/util/jar/TestVersionedStream gets Assertion error

[Steve Drach]

Hi,

Please review the following changeset that creates a replacement for the TestVersionedStream test.  The previous test occasionally failed on Linux hotspot nightly testing due to jar tool sometimes changing the order of the entries.  The new test specifically sets the order of the entries and tests both possible orders.
