python3-cryptography: Upgrade 3.0 -> 3.1

Upgrade to release 3.1:

- BACKWARDS INCOMPATIBLE: Removed support for idna based
  :term:`U-label` parsing in various X.509 classes. This support
  was originally deprecated in version 2.1 and moved to an extra
  in 2.5.
- Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer
  supported by the OpenSSL project. The next version of
  cryptography will drop support for it.
- Deprecated support for Python 3.5. This version sees very
  little use and will be removed in the next release.
- backend arguments to functions are no longer required and the
  default backend will automatically be selected if no backend
  is provided.
- Added initial support for parsing certificates from PKCS7 files
- Calling update or update_into on
  :class:`~cryptography.hazmat.primitives.ciphers.CipherContext`
  with data longer than 231 bytes no longer raises an
  OverflowError. This also resolves the same issue in
  :doc:`/fernet`.
