android-initscripts: rework launch of android system services

We're launching the needed android services now through the android init system which is
modified to not do any low level setup like setting up /dev.

pulseaudio: configure it to be compatible with the android-audiosystem

* Pulseaudio needs to be start only when the android mediaserver is running as otherwise
  it will hang while accessing the audioflinger service through android-audiosystem
* We're overriding the default configuration with our own variant which will be extended
  soon to support the webOS audio system.
* We can't use udev based module autodetection while configuring manual alsa sink/source
  as this leads to access pulseaudio the alsa card provided by the device twice and having
  our kernel oopsing.
* always start in system mode
