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
