Because we renamed the "google" iconset to be the modern Google set, not what is now called the "googleblob" icon set, we need to make sure that our usually correct policy of not overwriting image files under `prod-static/` doesn't apply to files potentially being copied in for the emoji images. We fix this by just deleting the `images-google-64` directory on upgrade if it contains the googleblob version of the "hotdog" emoji. Fixes #10038.
