Update face lockout co-ex message

If face auth is locked out and fp is running, show "Use fingerprint to
unlock" instead of the "Not recognized. Use fingerprint instead" message.
The latter message didn't make sense because face auth didn't actually
run since face auth was locked out (too many attempts).
