Only log "a password is required" for "sudo -n" if a command is specified.

This means that it is not logged for "sudo -nv" and "sudo -nl".
We only log this message when sudo's -n flag is specified (and not
when the user presses ^C at the password prompt) so that there is
a record of failed non-interactive commands.
