Add whoogle instances to services.json

Whoogle is now eligible for Farside links. I haven't decided how I'd
like this implemented yet though. My idea is actually to refactor part
of Whoogle to work a bit better with this new "instance hopping"
paradigm -- namely, I'd like the config settings to be easily turned
into query params and appended to a farside link when a user's preferred
instance is blocked.
