pyproject_buildrequires: don't pass config_settings as kwarg

PEP 517 says that the argument should be named config_settings but
pip/pyproject-hooks and other build frontends just pass it as a
positional argument, so some build backends name this argument other
things. Even though those build backends are wrong, it still makes sense
to align pyproject-rpm-macros with what the other frontends do.
