ansible-lint: Add paths and files to exclude list.

Some YAML files used in the project are not Ansible playbooks and
should not be evaluated by ansible-lint. This change add the paths
and files that should not be evaluated to an exclude list, that
affects linter operations in CI and pre-commit scripts.
