Gracefully handle ENOTSUP in ConfigFileManager.chattr0#523

The `chattr0` method, which attempts to clear special file attributes (like 'i' for immutable) using `ioctl`, can fail with an `ErrnoException` and the error code `ENOTSUP` (Operation not supported) on certain filesystems or Android environments (e.g., noted on a Android 11 device). When `ioctl` fails with `ENOTSUP`, it means the underlying filesystem does not support the operation of setting/clearing these attributes. In this case, we can safely assume the file/directory is not immutable via this mechanism and treat the operation as a successful non-action. This commit updates `chattr0` to catch `ErrnoException` specifically and return `true` if the error is `OsConstants.ENOTSUP`, preventing unexpected failures in config file management.
