pulseaudio 1.1: convert to useradd.bbclass

The only thing that got lost in the conversion is the "Pulse Audio daemon" description:

root@beagleboard:~# grep pulse /etc/passwd /etc/group
/etc/passwd:pulse:x:999:1000::/var/run/pulse:/bin/false
/etc/group:audio:x:29:pulse
/etc/group:pulse:x:1000:pulse
