AppVeyor: Skip saving cache on non-master branches

Otherwise we run into situations where commits to stable branches induce very long build times, as they have to basically build from scratch but also invalidate the cache for future commits on the master branch. This commit also makes the cache folder branch-specific, but since it's still limited to 1 GB of total cache size, we don't enable it for non-master, as we would still run into issues with non-master build invalidating the master cache.
