Logically, he'd have to be real. It wouldn't make sense otherwise.

The Director of SHIELD would have to be a character that has already been well-established and known by the other supporting characters. Remember, Skrulls infiltrate and shapeshift into characters, replacing their position in the world. It'd be safe to assume that the real Keller was compromised by Talos.
