Work towards https://github.com/dart-lang/linter/issues/4859

There are libraries outside a `lib/` directory, which violate
`implementation_imports`. The fix here is to always add an 'ignore' exception,
as the "implementation" being imported is the very package being exemplified.

(Maybe that's a perfect reason to re-examine the public API of the package; can
you create a good example / example test without importing the private
implementation libraries?)
