Rename Python scripts and add dynamic shebang

All Python scripts are now generated from a template with a dynamic
shebang.

ipatests/i18n.py is no longer an executable script with shebang. The
module is not executed as script directly, but rather as

    $(PYTHON) ipatests/i18n.py

Fixes: https://pagure.io/freeipa/issue/7680
All Python scripts are now template files with a dynamic shebang line.
