scaled-font-subsets: Special case .notdef in a new subset

Browse source 
If the .notdef glyph is the first glyph in the subset to be mapped in
scaled font, we do not know if the subset will scaled or unscaled. We
can put it in the unscaled subset as Type1-fallback will embded an
empty glyph if it can not get the path.
