    toaster: improve image file suffix retrieval
    
    Refactor retrieval of suffix from image file path, making it a
    a method on Target_Image_File. This makes it easier to use this
    in the build dashboard for individual images, plus reduces the
    complexity of the code required to get all of the image file
    suffixes for a build.
