[GLUTEN-8627][VL] Fix cpp build and build script on MacOS (#8628)

Fix the cpp compilation error and make builddeps-veloxbe.sh work on MacOS.

Manually tested with ./dev/builddeps-veloxbe.sh --run_setup_script=ON --build_arrow=ON --build_type=Debug --build_tests=ON --build_examples=ON and also tested with switching OFF the build options and Release build type.

Note --build_benchmarks=ON still fails because the function to set CPU affinity on macOS is not supported. I will fix that in a separate patch.
