The correct question is "What do your friends call you?" This question is asking for the names or terms by which your friends refer to you. On the other hand, "How do your friends call you?" is not grammatically correct in this context, as it implies a method or manner in which your friends physically call out to you.
President Carter signs his name as "Jimmy Carter" so I presume his friends call him that.
