lint: ignore flake8 line too long for ignored types

Adding a `# type: ignore` comment to a couple of places triggered
flake8's line too long check.

Running `make reformat` did nothing for these - black has outstanding
design issues with line length and comments.

See psf/black#1713 for one example.

Instead of changing the line structure to accommodate, ignore these two
cases, at least until the types can be fixed and the comments removed.
