LOG: [llvm] Pass FFI CMake options through to runtimes (for offload) (#118807)

Pass the FFI-related CMake options through to runtimes, since offload is
building against libffi. This is needed when the system requires custom
`LIBFFI_INCLUDE` to build (e.g. on Gentoo where the headers are
installed to `/usr/lib*/libffi/include`).
