rustc: remove deprecated private_in_public lint

The `private_in_public` rustc lint is now deprecated and throws a
warning on each `cargo check`. According to the rfc [0] this lint is
being substituted by three other ones: `private_interfaces`,
`private_bounds` and `unnameable_types`.
`unnameable_types` is not yet stabilized [1], so it will throw a warning,
but we will be ready when it is :)
