build.sh: Update links to SDK

The download step failed with an error 404 Not Found, because it tried to fetch:
https://github.com/artoolkitx/artoolkitx/releases/download/1.0/artoolkitX%20for%20iOS%20v1.0.dmg

Updated the links to the SDK releases so that they correspond to their location on GitHub.
