Subject: [PATCH] dib-lint: validate json/yaml files

Look for files .yaml and pkg-map configurations, and try to load them
either as json or yaml. This way, invalid ones can be detected before
they are committed unnoticed.

Also, exclude .yaml files from being searched while checking bash and
python scripts.
