Disable the DDS and JPEG-2000 plugins when Qt version is 5.3 or later

Browse Source 
QtImageFormats 5.3 comes with DDS and JPEG-2000 plugins that support
more options and are generally better than our plugins. The only
advantage our plugins offer is that the Qt DDS plugin does not work on
sequential devices, while ours does. This is outweighed by other
improvements, though, such as supporting more variants.
