macOS CI: Upgrade Homebrew packages before installing
Travis-CI's macOS worker image currently has libpng installed at a slightly outdated version. Unlike "apt install", "brew install" will not upgrade a package that is already installed, and will exit unsuccessfully when asked to do so. There does not seem to be a Homebrew command for "upgrade these packages if installed, or install them if not installed", so the most straightforward way seems to be to upgrade everything before invoking brew install. Fixes: #987
