- Unconditionally enable AAC support now that fdk-aac-free is in
Factory (adapted from SR 936225 by Neal Gompa
)

- Makes sure if we're using wireplumber and pulseaudio that
we don't enable the audio devices in pipewire by requiring
wireplumber-audio or pulseaudio if wireplumber is installed
- Better integration with PulseAudio (bsc#1188516) made by tiwai:
* Add Requires pulseaudio-setup package for the extra setups
in the %post section
* Add the missing Recommends alsa-plugins-pulse to
pipewire-pulseaudio package
