python-build: add support for pyproject.toml files
A new PEP 517 (https://www.python.org/dev/peps/pep-0517/) has defined that
Python packages can be shipped without any `setup.py` file, and that a
`pyproject.toml` file is sufficient.
A `setup.py` shim layer is suggested as a method for running the build.
For these cases, we will add a support in the OpenWrt build-system to
provide the default `setup.py` shim layer in case this file does not exist,
but there is a `pyproject.toml` file.
We also seem to need to tweak the shim layer with the PKG_VERSION,
otherwise the detected version is 0.0.0.
We will need to see if this will be fixed later in setuptools{-scm}.
