[go/perfbot-sheriff] Reenable win7 rendering.desktop stories

On a specific bot, only the first story seems to fail consistently. This
has led to disabling stories one-by-one, in the hope that the bot would
turn green again. Since it didn't, keeping these stories disabled
doesn't seem to make sense. Thus, reenabling them. The bot will stay
red until we figure out what's causing the trace data loss.
