vfs_catia: run translation on stream names

With vfs_fruit option "fruit:encoding = native" we're already converting
stream names that contain illegal NTFS characters from their on-the-wire
Unicode Private Range encoding to their native ASCII representation.

Unfortunately the reverse mapping for stream names was not perfomed.
