System: NetBSD 11.99.4
Architecture: All
Machine: All
>Description:
I would like to propose a small adjustment to the NetBSD flag banner
ASCII art printed by libsa when no "banner=" lines are provided in
boot.cfg (currently used by only NetBSD/x86 and NetBSD/wii?).

```
\--..,__,.,--''_-,
\\          -'- .
 \\ _    _,--' ' `
  \\ ``''
   \\
    \\
     \\
```

If maintainers/users prefer to keep the current banner unchanged,
please feel free to close the PR.

>How-To-Repeat:
See bootloader banner
