Remove unused icon references from webui cookie view.

I couldn't find where in the code these were used and I couldn't find
them in the UI either ( chrome://settings/cookies ). I tried without
success to sleuth out when, if ever, these were actually used. js
lists don't show icons the way js trees do.
