setuptools made some changes regarding distutils for version 60. By adding the environment variable `SETUPTOOLS_USE_DISTUTILS=stdlib` setuptools will use the standard library version of distutils and succeed building webkitcorepy. Otherwise, it will fail an assertion with a stack trace similar to this: https://github.com/pypa/setuptools/issues/2993 We'll need to take this into account when we bump our setuptools requirement.

Specifically: we should drop our usage of distuils, given it's deprecated and going away.
