Cycles: Fix T49952: Bad MIS sampling of backgrounds with single bright pixels

With this fix, using a MIS map resolution equal to the image size for closest imterpolation or twice the size for linear interpolation gets rid of all fireflies.
Previously, a much higher resolution was needed to get acceptable noise levels.
