crypto: digest: match driver name if no algo name matches
The digest command lists all registered digest implementations, but
there's no way to select a specific implementation when another higher
priority one exists for the same algorithm. Let's support this, by
having digest_algo_get_by_name fallback to look up by driver name if an
exact match couldn't be found by algo name.
