[gimp] app: get rid of gimp_get_backtrace().

    app: get rid of gimp_get_backtrace().
    
    It is not used anywhere anymore and can be replaced by the more powerful
    gimp_stack_trace_print() (which can also allocate a string containing
    the backtrace, hence is a proper replacement call).
