    stdio: Suppress clang warnings for tst-vprintf-width-i18n.c
    
    Clang issues the following warning:
    
      tst-vfprintf-width-i18n.c:51:34: error: invalid conversion specifier '1'
      [-Werror,-Wformat-invalid-specifier]
        TEST_COMPARE (sprintf (buf, "%I16d", 12345), 16);
                                     ~~^
    
    Since it does not how to handle %I.
