kuksa-val: Update to 0.3.1

Changes:
- Update kuksa-val to a commit that includes the 0.3.1 release and
  some other fixes past that. Our local patches have been updated.
- Rework and rename the kuksa-viss-client recipe for the upstream
  switch to kuksa-client as the name. Our local patches have been
  updated.
- Update kuksa-dbc-feeder to a commit that supports the kuksa-client
  library changes that come with 0.3.1. Our local patches have been
  updated, and a new local patch has been added to fix the token file
  configuration option behavior, this will be worked with upstream.
  Upstream changed the configuration file format, so our local one
  has also been updated to match.
- Update the parsing of the DBC feeder configuration file in the
  can-dev-helper.sh script to work with the new format.
- Update kuksa-val-agl recipe to not install AGL signals overlay
  for VSS, as that has been replaced with the use of the vss-agl
  package.
- Add installation of vss-agl to packagegroup-agl-ivi-services so
  the AGL specific signals and DBC configuration will be available.
