Revert "igraph: Build only the static lib"

This reverts commit 4b1d6dd.

Installing the Python package [python-igraph][1] importing it fails
with the error below.

    $ pip install --user leidenalg
    DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

Somehow it’s not linked against stdc++ correctly? [Missing stdc++ in during
linking?*][2] might be a similar issue.

Anyway, having the shared library for igraph around, python-igraph builds fine
and can be imported too. So add it back again.
