python3-pyzmq: Upgrade 20.0.0 -> 21.0.1

Upgrade to release 21.0.1:

- drop support for Python 3.5. Python >= 3.6 is required
- mypy type stubs, which should improve static analysis of pyzmq,
  especially for dynamically defined attributes such as zmq
  constants. These are new! Let us know if you find any issues.
- support for zero-copy and sending bufferables with cffi backend.
  This is experimental! Please report issues.
- zero-copy support in CFFI backend (send(copy=False) now does
  something).
- Support sending any buffer-interface-providing objects in CFFI
  backend.
- Errors during teardown of asyncio Sockets
- Missing MSVCP140.dll in Python 3.9 wheels on Windows, causing
  vcruntime-redist package to be required to use the Python 3.9
  wheels for pyzmq 20.0
- pyzmq-21.0.1 only changes CI configuration for Windows wheels
  (built with VS2017 instead of VS2019), fixing compatibility with
  some older Windows on all Pythons and removing requirement of
  VC++ redistributable package on latest Windows and Python < 3.8.
