Nicholas S. Husin 0f039f3a4a ssh: sanitize various error messages ...

Similar to CL 780180, sanitize other error messages that are controlled
by the remote peer, to avoid potential injection of control characters.

Also remove sanitizeString usage as it is not strictly needed to escape
error messages safely, and for consistency with how we sanitize other
error messages throughout the codebase.

BannerDisplayStderr is left unsanitized for now, as it is one instance
where we might actually want control characters for valid reasons (see
golang/go#80302).

Updates golang/go#80302
Fixes golang/go#80301
