simple_can_simulator: support different interface for LIN messages
Add a "--lin-interface" option to simple_can_simulator.py to allow specifying a different CAN interface for the cruise control LIN messages from the steering wheel in the demo setup. This allows pointing at the sllin0 interface in the full demo setup that is configured with the agl-demo-preload feature. Previously the CAN messages for the LIN events were bridged to the primary CAN interface, but this has proven unreliable in practice.
