fighting a losing battle against the py-cryptography rustification, part 3

Re-import the last version of py-OpenSSL without a hard unnecessary
dependency on rustified py-cryptography


(nia)

pyOpenSSL is a Python module that is a rather thin wrapper around (a
subset of) the OpenSSL library.  A lot of the object methods do
nothing more than call a corresponding function in the OpenSSL
library.

This legacy version is the last version supporting non-Rust
platforms (as well as, coincidentally, Python 2.7).
