[xharness] Skip the 'dont link / AssemblyBuildTarget: SDK framework (…

…release)' variation by default for tvOS. Fixes #xamarin/maccore@2282.

This test variation ends up being too big (1.5 GB), so it doesn't install
properly and the app crashes at startup.

So just skip it.

Fixes xamarin/maccore#2282.
