pythonPackages.cairocffi: v1.0.2 -> v.1.1.0

The tests were failing due the switch to pytest5.
This issue has been addressed upstream in
https://github.com/Kozea/cairocffi/commit/a500f208660ba9861828a2a92b32c33565ee18fd
which is included in v.1.1.0, so bumping the version and
updating the old patch.
