Subject: Remove run-time dependency on cffi

On Debian we ship a separate cffi-backend package (without the cffi
.egg-info), that just contains the run-time backend. This is all that
cryptography requires at runtime.

However, pkg_resources is pedantic and complains if it can't find
expected run-time dependency's .egg-info. To, avoid the problem, we drop
the dependency.
