python3-pip: inherit setuptools_build_meta

Upstream provides a pyproject.toml which declares setuptools.build_meta
as the backend for PEP-517 packaging.

We bootstrap the -native installation by simply unzipping the wheel to
PYTHON_SITEPACKAGES_DIR, so that all other recipes can use pip to
install wheels (as intended by upstream).

Check for presence of ${D}${bindir}/pip and remove if found (this was
originally to make sure Python2 pip was the default).
