Use the CFF program directly for CID fonts wrapped in OpenType FontFile3 ...

When a CIDFontType0 descendant has its program in a FontFile3 stream with
/Subtype /OpenType, the OTF wrapper sometimes lacks a usable cmap and the
CID→GID mapping only exists inside the embedded CFF itself. In that case
the OpenType-table path produces wrong glyphs, so route the font through
CFFFont and let it consume the inner CFF directly.
