description:
Add new BOOTSTRAP_SETUPTOOLS variable.

setuptools is one of the basic methods to install python packages.
However, since 34.0 it does not provide its dependencies any longer;
so they need to be installed from pkgsrc.

For bootstrapping, python itself comes with a copy of (pip and) setuptools.
Use this copy to install the necessary packages. They need to be
marked by BOOTSTRAP_SETUPTOOLS=yes for this.
