wireplumber: update to 0.4.12, drop dbus check from service file
https://github.com/void-linux/void-packages/pull/39720

Description:
- I tested the changes in this PR: **YES**
- I built this PR locally for my native architecture, (x86_64-musl)

According to https://gitlab.freedesktop.org/pipewire/wireplumber/-/issues/237 and https://forum.artixlinux.org/index.php/topic,4230.0.html , DBUS is not required, so I dropped it from the service file: everything is working as expected.
(No dbus, no elogind, no membership in audio group: just using seatd and run wireplumber as root using the provided service, my user is member of pipewire group.)
