cygwin-standard: argon2-cffi build fails: Fix up dependencies of cffi

[mkoeppe]

On cygwin-standard (https://github.com/mkoeppe/sage/runs/2000089431?check_suite_focus=true)

Setting up build directory for argon2_cffi-20.1.0
...
    ERROR: Could not find a version that satisfies the requirement pycparser
    ERROR: No matching distribution found for pycparser

This is actually an install-requires of cffi, which comes in because argon2-cffi is a PEP-517 package.

We also update cffi to the latest version, from 1.14.4 to 1.14.5.

Depends on #31279

Sure, looks straightforward enough.
