pipewire: remove libpulseaudio-pipewire from repos.
https://github.com/void-linux/void-packages/pull/32200

Description:
The packages for this are [still around on repos](https://voidlinux.org/packages/?arch=x86_64&q=libpulseaudio-pipewire), I think it's about time for those to go.
This subpackage [was deprecated with the upgrade to PipeWire 0.3.18](https://github.com/void-linux/void-packages/pull/27279).
