Subject: [PATCH] Don't crash on Android

If the platform plugin does not support the features needed
for QQuickWidget, then don't try to use it. This is a minimal
change to stop applications from crashing: it does not give
the application a way to find out if QQuickWidget is supported,
since that would mean new API, which we can't do in a patch
release.
