From: Luca Boccassi <luca.bocca...@microsoft.com>
The pkg_resources Python module is useful by itself, for example for
automatic loading of resources shipped in a Python package.
Add separate packages for it, so that users can depend on them
individually and avoid pulling in the entire setuptools, which
include scripts to download other packages, which might not be
desired on minimal images.
Other distributions like Debian and Ubuntu already split setuptools
and pkg-resources in this way.
The setuptools packages now depend on the new pkg-resources packages,
to avoid regressions for other packages that depend on them
already.

v2: restrict new RDEPENDS to class-target. As advised by Alexander, bitbake
cannot resolve native rdeps that mention package names rather than
recipe names.
v3: manually add RPROVIDES to the native class instead of restricting the
RDEPENDS to the target class as a better workaround. Also document why
the package is being split.
