Fix linking to stdlib with Maven and CLI

Fixes https://github.com/Kotlin/dokka/issues/551 by adding default links in each runner. This should probably be done in one place later on, but I don't see a good place to do it. We can't add it in DokkaGenerator without copying the whole configuration to some default implementation and we can't do it in ExternalDocumentationLinkResolver without redoing it in PackageProvider
