sdist: no way to include generated spec file in source.

No way to tell sdist to include the generated rpm spec file in tarball.
this is usefull when trying to generate the rpm using rpmbuild -tb
(rrpmbuild will use the specfile from tarball to build the package. This is more friendly than extracting the tarball and running python setup.py bdist_rpm; cd ..; \rm -rf )

Start by tracing how sdist creates its tarball and how setup.py bdist_rpm generates the spec file. Check whether the sdist archive can include that generated file, then verify the resulting tarball can be passed to rpmbuild -tb and that the spec file is present.
