typing: induce pytype to use the standard `attr` instead of the vendored copy

What was previously happening with the vendored copy was that pytype would stub
out all(?) classes that were decorated with `@attr.s` as `Any`.  After this, we
get a ton of classes defined, and numerous fields and methods now have proper
types.
