dbus: Fixes Bug#13094 - dbus daemon continues running after uninstall

- The uninstall.sh script had stop_service ${NAME} but the package name is dbus while the
   initscript is named messagebus. Therefore the stop_service never stops the dbus daemon.
- This patch changes the line to stop_service messagebus
- The install.sh script already has start_service messagebus
- Bump PAK_VER for dbus
