Bug: LLAMAFILE = 0 in `llama_print_system_info` even though compiled with `-DGGML_LLAMAFILE=ON` and can see set during compilation

What happened?

In llama_print_system_info in llama.cpp, the output is LLAMAFILE = 0, even though can see that it's enabled (from the output Using llamafile when building).

When building with -DGGML_LLAMAFILE=ON (the default), the C #define for GGML_USE_LLAMAFILE is set in ggml/src/CMakeLists.txt, but llama.cpp (which contains the llama_print_system_info never defines that to be true.

Could perhaps fix by duplicating the logic add_compile_definitions(GGML_USE_LLAMAFILE) in ggml/src/CMakeLists.txt to CMakeLists.txt? I'm not sure what best practices are for cmake.

Low priority since this is still set / used by ggml code but definitely surprising/incorrect in the debug info.
