python3-wheel: inherit flit_core

Backport pyproject.toml from flit-backend branch.
Inherit flit_core class to build
Inherit pip_install_wheel to install wheels for target

We need to bootstrap python3-wheel-native in order to have bdist_wheel
available to python3-setuptools-native and the refactored
setuptools3.bbclass. Simply unzip the wheel into
PYTHON_SITEPACKAGES_DIR for class-native.
