graphics/cuneiform: Slap on a band-aid and fix build with Clang 6

- Code base compiles under USE_CXXSTD=gnu++98
- Use options helpers
- Fix no-op IMAGEMAGICK option; the patch to disable it no longer
  did anything.  With ImageMagick installed in the build environment
  ImageMagick support was enabled regardless of option state
- Deprecate.  It's unmaintained upstream and the build problems will
  likely get worse over time
- Take maintainership
