RFR: 8258732: runtime/cds/appcds/dynamicArchive/DynamicArchiveRelocationTest.java fails [v2]

[Calvin Cheung]

> On Windows, sometimes the OS picks 0x0000000800000000 as the requested archive base address. This resulting in runtime relocation won't happen. The test expects the `Unmapping region #3` output trace which won't be there if there no relocation. The fix is to adjust the test to look for another output trace in case the matching of the original trace has failed.

> Testing: tier 1 - 4.
> Also ran the test 50 times with tier4 vm options on Windows.
