When building a .nuproj project that referenced a Xamarin.Android
project _GetReferencedPackageContents would fail when
Xamarin.Android 9.4 was installed with the error:
The "FilterAssemblies" task was not given a value for the required
parameter "DesignTimeBuild".
To workaround this the DesignTimeBuild property is set, if not already,
and passed to the GetPackageContents.
