LOG: [mlir-cpu-runner] Pass --exclude-libs to linker when building runner (#122329)

This fixes a conflict between the version of LLVM linked against by the
runner and the unrelated version of LLVM that may be dynamically loaded
by a graphics driver. (Relevant to #73457: fixes loading certain Vulkan
drivers.)
