Denton Gentry 878a20df29 net/dns: add GetBaseConfig to CallbackRouter.
Allow users of CallbackRouter to supply a GetBaseConfig
implementation. This is expected to be used on Android,
which currently lacks both a) platform support for
Split-DNS and b) a way to retrieve the current DNS
servers.

iOS/macOS also use the CallbackRouter but have platform
support for SplitDNS, so don't need getBaseConfig.
