This reverts commit d5efa74.
The original intention of providing a distutils fallback has not gone away. These three extra lines will almost never be used, as most people have setuptools or install with pip anyway, and at the same time it serves as a very low-maintenance solution for people who do want to bootstrap setuptools.
Bootstrapping setuptools without vendored six (and pyparsing) is a valid use case. Although setuptools by default ships with vendored dependencies, it supports removing the contents of the _vendored/ directory and falling back to an installed version of six.py -- and thirdparty vendors of setuptools, such as Arch Linux and OpenSUSE, actually make use of this and need to be able to bootstrap the dependency tree of setuptools itself.
