[cairo] patch for crash in cairo-ft-font.c

[Robert O'Callahan]

Yesterday I encountered a crash in  _cairo_ft_unscaled_font_create_glyph
--- in "glyphslot = unscaled->face->glyph", unscaled->face is null. The
attached patch fixes it and appears logical although I'll be the first
to admit I haven't really understood this code.
