    flatpak: raise priority of build-system discovery
    
    This should be higher than the build systems priority because the project
    is explicitly telling us what it should be.
    
    Projects opened with the file-chooser will have the plugin that provided
    the file-filter pinned when opening the project. That will get saved to
    the recent-info so that followup loads get the same plugin, so having a
    higher priority than the build systems themselves is fine.
