travis: force usage of Xcode 8.3 image Travis has upgraded the default Xcode images from 8.3 to 9.4 on 31st July 2018, including an upgrade to macOS 10.13. Unfortunately, this breaks our CI builds on our maintenance branches. As we do not want to include mayor changes to fix the integration right now, we force use of the old Xcode 8.3 images.
