RFR: 8261753: Test java/lang/System/OsVersionTest.java still failing on BigSur patch versions after JDK-8253702 [v2]

[Christoph Langer]

> After the fix for JDK-8253702, the test java/lang/System/OsVersionTest.java still fails on BigSur versions that have a patch version (> 1), e.g. on macOS Big Sur 11.2.1, and where the JDK was built with xcode < 12.
> 
> java.lang.Error: 11.2 != 11.2.1
> 
> This is a proposal to relax the test and throw a SkippedException in such cases.
