security/py-pycryptography: Fix build on FreeBSD 9.3
Modern py-cryptography requires a more modern OpenSSL. This switch to
requiring OpenSSL from ports is a disruptive change, but it will protect
these users from the recently patched vulnerabilites.
Support for OpenSSL 0.9.8 was removed in pycryptography as of version 1.4.
The last release to support OpenSSL 0.9.8 was 1.3.4 which is still
vulnerable to the HDKF key generation bug. It appears that version 1.4
did build successfully on FreeBSD 9.3, but upstream had abandoned
support for OpenSSL 0.9.8 at that point so it is unclear if it was fully
functional.
