Add meta-agl-kuksa-val

Add new meta-agl-kuksa-val layer, and populate it with the base
KUKSA.val databroker and VSS schema recipes from meta-agl, as well
as the recipes for the Python modules they depend on.

Additional changes:
- Installation of AGL-specific configuration has been removed from
  the kuksa-can-provider recipe.  It now packages the upstream
  example/test configuration in a new kuksa-can-provider-conf-example
  package that can be replaced via the RPROVIDES scheme.  Some minor
  tweaks for paths are made to the upstream .ini file to match
  FHS expectations.

+Subject: [PATCH] Remove protobuf-src usage
+
+The vendoring of a protoc and libprotobuf build that was added in
+commit 890703c9 by using protobuf-src is not really workable with
+OpenEmbedded / Yocto Project, and somewhat undesirable for any
+distribution package builds when it comes to transparency and
+reproducibility.  Remove it so that building in OE/YP will work.
