[gimp] app: use sRGB gamma in u16 precision

    app: use sRGB gamma in u16 precision
    
    This permits editing sRGB profile PNGs and other formats using sRGB storage,
    without this editing a 16bit bpc PNG in u16 mode would cause banding in the
    shadow areas on import. File that do not have an sRGB like gamma should be
    promoted to a higher bit-depth on import.
