[XeTeX] new version of HarfBuzz

[Jonathan Kew]

I believe that xetex should be unaffected by that bug, because that was 
an issue with the harfbuzz interface to graphite, but xetex uses 
graphite directly without going through the harfbuzz layer (provided you 
load the font with the /GR option, or whatever the fontspec equivalent 
of that is).
