goldix patches — cuframes addin + base-linux64 customizations

addins/cuframes.sh:
  Activation hook (./build.sh linux64 gpl cuframes) — overrides FFmpeg repo
  на gx/ffmpeg-patched branch n7.1-cuframes (наш fork с vf_cuda_grid,
  cuframesdec.c). Exports FFBUILD_HAS_CUFRAMES для 50-libcuframes.sh.

images/base-linux64:
  Dockerfile + ct-ng-config modifications (build system tweaks для нашего
  environment).
  preload/ — pre-downloaded gmp-6.3.0 + zlib-1.2.12 tarballs (offline build
  / cache miss workaround).
