alsa: Fix bug#13087 remove services entry

- alsa has an initscript but it is not starting and stopping a traditional daemon service.
   The initscript loads some alsa modules and then restores the asound.state file
- This patch updates the PAK_VER number and removes the services entry and explicitly
   adds alsa in for the initscript installation.
- Additionally this patch also adds the installation of a backup include file for alsa
   which savces the soundcards status file asound.state
