    gdb pretty-printers: fix StringPrinterHelper for gdb 8.0
    
    Latest gdb release "lazy_string" validates the array size:
    
      Traceback (most recent call last):
        File "/work/lo/master/solenv/gdb/libreoffice/util/string.py", line
    29, in to_string
          return self.make_string(data, self.encoding, len)
        File "/work/lo/master/solenv/gdb/libreoffice/util/string.py", line
    66, in make_string
          return data.lazy_string(encoding, length)
      gdb.error: Length is larger than array size.
    
    rtl_uString has "sal_Unicode buffer[1];", which is a lie
    as the real size is the same as "length".
    
    Taking the address of "buffer" appears to avoid the exception.
