generic/062 uses getfattr to dump xattrs for a directory tree, then deletes and recreates that directory tree, then dumps the xattrs again and compares the dump to the original. This was failing when run on ext4 with encryption enabled because getfattr's output is in readdir order, but ext4 encryption by design chooses unpredictable encrypted filenames for each new directory, causing the readdir order to change after backup and restore. It is not really a valid assumption that the readdir order will always be the same, so update the test to sort the filenames, removing this assumption.
