Subject: [PATCH] Skip testCreateParentDirectories_noPermission when running as
 root

When running tests as root, filesystem permission checks are bypassed,
so MoreFiles.createParentDirectories succeeds instead of throwing
IOException. Skip the test in this case, similar to the existing
Windows skip.

Fixes #7328
