* pylint doesn't install tests anymore, so we don't need to remove them
* manpages were old and so they were removed upstream
* moved distfiles from pypi to github, because pypi releases don't contain tests
* updated python3-astroid, because they are tightly coupled and pylint 2.9 needs astroid 2.6
* adopted both packages
