Setup on Mac M1 is broken with /usr/local/ path hardcoded

Problem description

I was running the setup-macos.sh script after rebasing to the latest. The install_build_prerequisites method has /usr/local/bin/ path hardcoded to check for ccache. This fails on Mac M1.

On Velox build, this error is ignored and proceeds to next steps. But on Prestissimo, setup fails at this point.

What is the permissions of your /usr/local/bin directory? Users should usually be able to move to that folder.
