Title: Brew install or upgrade - fixes MySQL recipe fails if older version of MySQL is installed

This changes #brew_install to run "brew update #{package}" when is package is already installed instead of ignoring.

This addresses an issue we had with #brew_install for mysql which failed because the `brew --prefix mysql` returns a path for the expected version of MySQL, not the currently installed version of MySQL.
