[crac] RFR: 8362837: [CRaC] jdk/crac/MXBean.java can fail on macOS [v4]

[Jan Kratochvil]

> The CI runs fine but locally (Linux Fedora 42 x86_64) it is failing for me - for any testcase trying to use OutputAnalyzer for the restore-only part. Such testcases failing for me are for example:
> - test/jdk/jdk/crac/fileDescriptors/CheckpointWithOpenFdsTest.java
> - test/jdk/jdk/crac/fileDescriptors/LoggingFileOpenTest.java
> - test/jdk/jdk/crac/SecureRandom/ReseedTest.java
> 
> It does not implement the part
> 
>> close to 0
> 
> as that is the problem being fixed.
