CameraRGBD: set VTK QSurfaceFormat before QApplication

Browse Source 
On macOS the embedded QVTKOpenGLNativeWidget (CameraViewer's cloud view)
crashed on first paint: VTK called a null GL function pointer
(vtkOpenGLVertexArrayObject::Bind -> 0x0) because no compatible OpenGL
context was set. Set QSurfaceFormat::setDefaultFormat(
QVTKRenderWidget::defaultFormat()) before constructing QApplication, as
the main rtabmap app already does.
