Add patch to enable building the sllin driver against kernels 5.9
or newer.

Changes:
- Add a can-dev-mapping-helper.sh script and systemd unit to drive
it, the script checks if the CAN devices specified in the low-can
configuration file /etc/dev-mapping.conf exist, and if not brings
up corresponding virtual CAN devices.
- Add a systemd over-ride conf file for agl-service-can-low-level
that makes can-dev-mapping-helper a dependency. This should ensure
that the low-can binding always starts even if there are no physical
CAN hardware devices.
- Added a Before statement to sllin-demo.service to ensure that it
will run before can-dev-mapping-helper and ensure that lin_config
can create sllin0 correctly.
- Removed the sllin-demo-virtual systemd unit, as it will no longer
be required with can-dev-mapping-helper.
- Updated the /var/run paths in sllin-demo.service and associated
start_lin_demo.sh script to quiet systemd warnings about /var/run
usage.

To enable seeing the steering wheel LIN messages on the cluster board
for the planned CES demo, a systemd unit that wraps the use of candump
in bridging mode is added when the agl-cluster-support feature is
enabled. To make sure that the sllin0 interface is always available
for testing without the specific demo LIN hardware, a vcan interface
is set up as sllin0 when the ttyUSB0 device representing the serial
adapter for the LIN transceiver is not present. Since this virtual
sllin0 interface is very useful for general testing of the steering
wheel event support up through the low-can and signal-composer stack,
it has not been hidden behind agl-cluster-demo-support.

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.
