Merge #3697

3697: update itertools version to 0.9.0 r=matklad a=JoshMcguigan

Updating `itertools` version per [feedback on #3689](#3689 (comment)) from @SomeoneToIgnore.

Worth noting that `chalk` still uses `itertools` v0.8.2, so perhaps it is worth a PR to update that repo as well so we don't have to build both versions?
