python3-ipython: switch to PEP-517 build backend

- The project has a proper pyproject.toml which declares the setuptools.build.meta PEP-517 backend.
- The PyPi package name (defaults to PN without the python3- prefix), so there is no need to set PYPI_PACKAGE as ipython, it is by default.

Fix:

WARNING: python3-ipython-8.26.0-r0 do_check_backend: QA Issue: inherits setuptools3 but has pyproject.toml with _build_meta, use the correct class [pep517-backend]
