Install *.yaml files from meta-schemas and schemas

The Arch Linux package uses the following commands to build and install
the project:
  $ python -m build --wheel --no-isolation
  $ python -m installer --destdir="$pkgdir" dist/*.whl

The installed output in $pkgdir however does not contain the *.yaml
schemas from dtschema/meta-schemas and dtschema/schemas. Add setuptools
configuration so the *.yaml files are installed.
