Avoid installing setuptools 45 on Python 2.
Because Requires-Python is disabled for Python 2 to allow this declared-incompatible version to install on Python 2, the build-requirements must exclude installing setuptools 45 during the build-system setup.
Because Python 2 tests are only needed for internal validation, and because the latest pip is already installed, the build-system can rely on `backend-path = ["."]`.
Fixes #1996.
