Move authentication failure logging to log_auth_failure(). Both of these call audit_failure() for us. This subtly changes logging for commands that are denied by sudoers but where the user failed to enter the correct password. Previously, these would be logged as "N incorrect password attempts" but now are logged as "command not allowed". Fixes bug #563
