Expose SkFaceRec less.

The SkFaceRec class is some data which needs to remain alive for the
life of an FT_Face. ref_ft_face returns SkFaceRec, but confusingly
unref_ft_face takes an FT_Face. Since no one was using the SkFaceRec
for anything other than accessing the FT_Face, have ref_ft_face
return FT_Face instead and remove the unused SkFaceRec pointer from
the scaler context.
