I think this is the better solution to the libffi / ctypes issue. It
also fixes python-minimal <at> 3 to use the bundled libffi. We added libffi
to python-minimal <at> 3's inputs in
d0b73960db051baa468fc1a0fbab21fa9f89f885 to work around a similar issue.

In Python 3.7, the bundled libffi will be removed, and we will have to
build our minimal Python-3 variant with an external libffi package:

https://bugs.python.org/issue27976

Here's a patch that fixes this problem for python-minimal <at> 2. I don't
want to change python-minimal <at> 3 this late in the core-updates cycle; we
can do it in a python-updates branch after core-updates.
