package/python-bleak: use correct pep517 build backend

We need to migrate python-bleak to the pep517 poetry-core backend
as setuptools is not supported when building with a pep517 frontend.

This package currently builds using setuptools as we do not yet
use setuptools with a pep517 build frontend. The package contains
a setuptools fallback which only can be used when using setuptools
without a pep517 frontend as the pep517 frontend will only use the
build backend specified in the package pyproject.toml which is
poetry-core and not setuptools.
