mpd: depend the full variant on pulseaudio instead of pulseaudio-daemon

mpd: depend the full variant on pulseaudio instead of pulseaudio-daemon

The full variant of mpd depends on pulseaudio-daemon, so it was not
possible to use the other pulseaudio variant with avahi.

Both pulseaudio daemons provides package pulseaudio, so users can choose
which variant suits them best.
Let's change the dependency to pulseaudio.

Fixes: #19187
Fixes: 2ed62adc5914 ("mpd: enable pulseaudio in full package")
