Prevent apk from pulling in pipewire-pulse instead of pulseaudio, as
this leads to various audio issues with Phosh in postmarketOS (volume
buttons not working, no sound in various applications).
Pipewire will be a great replacement for pulseaudio, but let's rather
enable it intentionally for Phosh once we fixed everything that's
currently breaking with it. Without this patch it may get installed when
installing or upgrading other packages (not entirely sure how it gets
triggered yet, but I have seen it myself multiple times and we've gotten
reports about it).
