py-ipython: missing dependencies on py-typing and py-pathlib2 for some python versions

[Ionic (Mihai Moldovan)]

Following error occurred when installing py34-ipykernel (as a dependency of something else):

Turns out: that's right.

According to ​ipython's setup.py file, we need to depend upon py-pathlib2 for python 3.3 and py-typing for python 3.4 and below.

I'll attach a patch for you to review. If you're okay with it, I can also commit it.

py-ipython: add py-typing dependency for py34 variant

Fixes: #54868

[Ionic (Mihai Moldovan)]

Thanks for applying the fix.

I have to reopen this ticket, since we do need the revbump, though, since py-ipython installs fine without this dependency (because something doesn't seem to be checking the extra dependencies), but py-ipykernel (and maybe other dependencies) will fail to build.
