pylint: ignore possibly/used-before-assignment as it is prone to FP

It does no control flow analysis, and upgrading to pylint 3.2.0 produced
many incorrect warnings.

Also ignore contextmanager-generator-missing-cleanup for now. It has FP
when there is no code after a yield (and thus no cleanup needs to be
handled), which is what we do. Currently under discussion upstream:
