systemd/pipewire: lower preferance to install pipewire-pulse than pulseaudio

For some reason, apk preferred to satisfy g-s-d's pulseaudio dependency
by pipewire-pulse-9991.4.9-r1 (with k=1) and not pulseaudio-17.0-r7
(with k=10), and therefore didn't respect provider_priority but pkgver.

This then resulted in the apk solver preferring
pmos-base-ui-audio-pipewire over -pulseaudio, because the
!pipewire-pulse dep by -pulseaudio wasn't satisfiable.
