fixed: pulseaudio started on non-pulse systems by standalone mode
Fix a regression of r34013 in which pulseaudio was started on systems
with pulseaudio disabled when running the standalone mode script. See
ticket #9247 for details.
This is done by switching to use start-pulseaudio-x11 with pulse-session
as fallback (the latter was used before r34013) instead of pulseaudio
