- Rework package:
* Drop support for multiple python versions and build only for
default python3; this is a command line app, not a python
library.
* Switch to pyproject_* macros for build.
* Keep zero-sized template code which is used and filled in when
producing generated code.
* Add Provides: glad to package.
* Drop python-Jinja2 from BuildRequires; run-time but not build
dependency.
* Drop python-setuptools from Requires.
* Delete unnecessary hashbang from a non-executable file.
* Drop update-alternatives post scripts and related requires.
* Add Obsoletes against current pythons packages.
