Quantize kerning adjustment, otherwise all the metrics hinting effort will

* pango/pango-ot-buffer.c (apply_gpos_ltr), (apply_gpos_rtl),
(pango_ot_buffer_output):
* pango/pango-types.h:
* pango/pangofc-font.c (pango_fc_font_kern_glyphs):
* pango/pangofc-private.h:
Quantize kerning adjustment, otherwise all the metrics hinting
effort will be ruined by a non-whole-pixel kerning value.
In the future we want to take lsb_delta and rsb_delta into the
game before quantizing the adjustment here, but we don't have
those values handy right now.
