Support Go 1.13 error chains in
Imagine module A imports module B and both use `pkg/errors`. A uses `errors.Cause` to inspect wrapped errors returned from B. As-is, B cannot migrate from `errors.Wrap` to `fmt.Errorf("%w", err)` because that would break `errors.Cause` calls in A. With this change merged, `errors.Cause` becomes forwards-compatible with Go 1.13 error chains. Module B will be free to switch to `fmt.Errorf("%w", err)` and that will not break module A (so long as the top-level project pulls in the newer version of `pkg/errors`).
