Goober is a term for peanuts in general, it’s not specific to African peanuts. It can indeed be used colloquially to refer to a simpleton or silly person, but it doesn’t have any particular racial connotation.
The only connection to Africa I could find is the etymology, as the word was borrowed from an African language. Considering 75% of English’s vocabulary (including swear words) is borrowed from other languages, I don’t think this is a particularly pertinent thing to take issue with. I mean, unless you have a source showing I’m wrong. No source I could find points to any racist connotation for the word “goober”.
