pulseaudio: sync patches with Mer

* we're now using a patchset from Mer (see github.com/mer-packages/pulseaudio, tag
  4.0+git8) which provides the base for pulseaudio-modules-droid which will utilizes the
  Android Audio HAL to enable Audio playback on Android based devices
* furthermore we're not shipping our own configuration with pulseaudio but will load this
  instead through the PULSE_SCRIPT and PULSE_CONFIG environment variables and put them
  into a pulseaudio-distro-conf package.
