dev-python/ipython: remove runtime dependency on matplotlib

ipython does not use or rely on matplotlib at runtime in any way. It
does contain imports for it, but these imports are only triggered by the
act of typing `%matplotlib` into the interactive shell, which is an
ipython "magic" that runs matplotlib with some enhanced context.

People who do not use matplotlib don't need to have its installation
forced, and people who do use matplotlib will have it installed before
interactively using it, much as they do when interactively using it with
`import matplotlib`.

It is intentionally not listed as an install requirement in setup.cfg,
although the matplotlib-inline module *is* listed as an install
requirement. (matplotlib-inline contains the actual implementation of
the magic, and is very lightweight, so it is not particularly
advantageous to add a USE flag for it. Users of matplotlib won't
automatically have the -inline module installed.)

Per the way other magic commands work, the correct place to notify users
about the availability of these is using optfeature.
