Subject: [PATCH] Make KeyError.message/2 private

It was introduced in https://github.com/elixir-lang/elixir/pull/7803,
looks like it was accidentally made public (no docs, no specs)

It shipped in Elixir v1.7 so technically this would be a breaking
change. I'm happy to deprecate/doc false it instead.
