[C++] [CI] macOS failures on githubactions runs

[asfimport]

Starting recently, we are getting filures on macos with c++ https://github.com/apache/arrow/actions/runs/1307843484

DocumentRoot is /usr/local/var/www.
320

321
The default ports have been set in /usr/local/etc/httpd/httpd.conf to 8080 and in
322
/usr/local/etc/httpd/extra/httpd-ssl.conf to 8443 so that httpd can run without sudo.
323

324
To start httpd:
325
  brew services start httpd
326
Or, if you don't want/need a background service you can just run:
327
  /usr/local/opt/httpd/bin/httpd -D FOREGROUND
