Description of changes

This package was disabled because upstream said "DO NOT USE" on PyPI, and because it depends on the unmaintained nose test framework. There's some nuance to the first point, however. As you can see by looking at the repository README, the full recommendation is that "no packages outside IPython/Jupyter should depend on it". Unfortunately, nbclassic is an actively maintained part of Jupyter which depends on ipython-genutils, so we have to keep it alive for now.

The options to do so are either to keep nose alive (as Arch does) or to migrate nose tests to pytest (as openSUSE does). I picked the latter option and imported the openSUSE patch. Three and a half years ago, openSUSE devs notified upstream at ipython/ipython_genutils#17, but upstream thought fully eliminating ipython-genutils was in the near future; it hasn't happened so far.
