audio/miniaudio update to 0.11.x

Hi guys

I hope you're doing well

I wanted to tell you that I'm currently working on games/jaggedalliance2
upgrade to 0.20.0 (
https://ja2-stracciatella.github.io/2022/11/14/release-0.20.0.html) which
brings support for newer miniaudio-0.11

That means that
https://cgit.freebsd.org/ports/commit/?id=e403b5a815496a076a0ee20df6439b8b0199fc75
(audio/miniaudio: Downgrade 0.11.9 -> 0.10.43) can be reverted when I'm
done.

I'll keep you posted!
