libpulseaudio: ditch downstream defaults in daemon.conf

To start pulseaudio manually as a daemon, you just need "-D", but
if you set daemonize=yes in daemon.conf, when you want start it
undaemonized, you will need "--daemonize=no".

We don't really need to set enable-shm to no explicitly.

Setting exit-idle-time to -1 may not be as preferred as when it was
when autospawn did not work.

There's no point setting log-target to stderr. auto works fine (or
perhaps even better) for us.
