cleanup py38-{numpy, scipy, matplotlib} dependents

[reneeotten]

Description

Another PR with update and/or removal of PY38 subports of packages that require py-numpy, py-scipy, or py-matplotlib. All these ports should be updated at some point to the latest upstream versions and removal of no-longer-supported subports will help in this (as it has shifted to meson as build system for the newer versions). Having only to worry about the upstream supported versions will make maintaining the port much easier.
