[HarfBuzz] variation selector support

Hi Behdad,

There seems to be a problem with the variation-selector support in hb_map_glyphs(); it doesn't account for the fact that the VS slots need to be eliminated from the buffer during char-to-glyph mapping. As a result, we end up with .notdef glyphs corresponding to the VS codepoints, even though the correct variants are chosen for the base characters.

The attached patch ought to fix this.
