Make /usr/local/* chowns non-recursive

Certain macOS AV tools that might come pre-installed in an
enterprise environment may install themselves into /usr/local
and may intercept calls to `chown` to avoid having their
ownership changed. Unfortunately, this causes the Homebrew
install step of strap.sh to fail on such machines with these AV
tools installed.
