Currently, lang/python38 and lang/python39 don't honor
DISABLED_EXTENSIONS because patch-issue20210 was removed when
lang/python38 was added to the ports tree. patch-issue20210 is still
present on lang/python36 and lang/python37.
Building with poudriere is not affected because builds are executed in a
clean environment.
Setup.local is the more canonical and recommended method for customizing
Python builds for shared extensions & third party libraries.
Support for a *disabled* marker in Setup files was introduced in Python
3.7, so backport this fix to it to keep consistency in the ports tree.
