games-util/input-remapper: 9999: Handle build system changes

The dev has dropped setup.py but continues to use setuptools.

Two patches introduced:
1. Dev has not specified a build-backend in pyproject.toml
2. mo-file generation manual execution (used to get handled by setup.py)

Also "pydbus" has been replaced with "dasbus"
