Update LIN demo to use lin-config
Changes include:
- Add patch to fix lin-config recipe build QA error.
- Tweak lin-config recipe to install lin_config as executable.
- Rework sllin-demo systemd unit and start_lin_demo.sh script to use
lin_config with an appropriate configuration file that enables
polling of the steering wheel adapter instead of just using
ldattach.
