harfbuzz: update 1.1.0 -> 1.1.2

Overview of changes leading to 1.1.2
Wednesday, November 26, 2015
====================================

- Fix badly-broken fallback shaper that affected terminology.
  https://github.com/behdad/harfbuzz/issues/187
- Fix y_scaling in Graphite shaper.
- API changes:
  * An unset glyph_h_origin() function in font-funcs now (sensibly)
    implies horizontal origin at 0,0.  Ie, the nil callback returns
    true instead of false.  As such, implementations that have a
    glyph_h_origin() that simply returns true, can remove that function
    with HarfBuzz >= 1.1.2.  This results in a tiny speedup.
