Actually package pulseaudio is needed instead of pulseaudio-utils.
Package pulseaudio-utils then gets drawn in by postmarketos-base-ui
sub-package pulseaudio.
For Xfce4 this is a cosmetic change because pulseaudio gets installed
as a dependency of pavucontol already. Keeping pulseaudio in the
_pmb_reccomends list makes sense to be clear which pieces are needed.
For MATE an explicit installation of pulseaudio is needed because it
doesn't use pavucontrol.
