The missing file for the unit tests was fixed upstream, which allows to
simplify the APKBUILD a bit.

Fixes: #10671

Added a patch to make it work with edge py3-setuptools.
Basically it removes the check against the version (since the version on edge is 41.0.0 and the min requirement is 36.2).

On cerbot 0.36.0 there is no longer certbot-postfix, that has been removed upstream.
Changelog does not mention this.
