RFR: 8325201: (zipfs) Disable TestPosix.setPermissionsShouldConvertToUnix which fails on Windows [v2]

[Eirik Bjørsnøs]

> Can I please get a review for this trivial change to disable the test `TestPosix.setPermissionsShouldConvertToUnix`?
> 
> This test was recently introduced in [JDK-8324635](https://bugs.openjdk.org/browse/JDK-8324635), but fails intermittently on Windows CI runs. (See [JDK-8325199](https://bugs.openjdk.org/browse/JDK-8325199))
> 
> To reduce CI noise, I suggest we simply add `@Disabled` for now on the failing test.  The actual fix of the failing test will be investigated and fixed as a follow-up PR.
