Use new module-level mypy suppression syntax.

mypy 0.990 contains the change python/mypy#13512, so
we are forced to use the latest & greatest way of specifying module-level
typing suppressions now.  Note that it is not possible to split these fixed
from the mypy update itself: Previous versions don't understand the new way
and the current version complains about the old way.  Great upgrade path!
