[iOS/tvOS] System.IO.Compression.Tests.ZipFile_Unix.UnixCreateSetsPermissionsInExternalAttributes fails on devices

Most likely not taking into account platform specifics re: permissions

The test fails with:

Assert.Equal() Failure
Expected: 3968
Actual:   896

Also affecting the release/6.0 branch. I'm disabling the tests there too: #68867

When this issue gets fixed, the fix needs to get backported to release/6.0.
