Make results of SDL.getRenderDriverInfo printable without causing errors

[oshyshko]

When running on macOS 10.15.7 + lts-16.29 (ghc-8.8.4),
SDL.getRenderDriverInfo produces an unprintable result (lazy errors).

This commit makes the results printable.

Here's a test that shows the problem:

#!/usr/bin/env stack
-- stack --resolver lts-16.29 script --package sdl2 --package text

module Main where

import           SDL

main :: IO ()
main =
    getRenderDriverInfo >>= mapM_ (\r -> do
        putStrLn $ "rendererInfoName r: " <> (show . rendererInfoName $ r)
        putStrLn $ "length (rendererInfoTextureFormats r): " <> (show . length . rendererInfoTextureFormats $ r)
        mapM_ print $ rendererInfoTextureFormats r)

-- before the change it fails with this output:
-- rendererInfoName r: "metal"
-- length (rendererInfoTextureFormats r): 16
-- ARGB8888
-- ABGR8888

Notice the trailing zeros returned by rendererInfoTextureFormats.
These are not addressed by the PR and presumably should be fixed at an another place.
