Since we're already linking against TensorFlow and want to keep the number of dependencies small, we should investigate alternative approaches in addition to the obvious solution to use dlib (which is the popular/standard way, see go-face). Pigo is a pure Go implementation for Face Detection, but it can not do Face Recognition.
