Hitting Jasserts OSX 11.1

[asimilon]

SystemStats::getOperatingSystemType assertion fails on macOS 11.1

Apple just released macOS 11.1 (which should hopefully fix all the problems on my M1), and this breaks an implicit assumption by juce::SystemStats::getOperatingSystemType - which the update was expected to be a 11.0.X (Apple stayed on version 10 for two decades, are they going to jump version every year now?). Everyone is likely to hit this assertion as the constructor of juce::TopLevelWindow happens to call it. Suggested fix at https://github.com/soundradix/JUCE/commit/d35ca96c50772c767c2e8c0…
