    examples: fix -Wformat warnings
    
    When size_t is not a typedef for unsigned long (as usually the case on
    Windows), GCC emits -Wformat warnings when using lu and lx format
    specifiers with size_t. Silence them with explicit casts to
    unsigned long.
    
    Closes https://github.com/curl/curl/pull/2721
