No, it is the other way round: If a xetex package is detected,
use_non_tex_fonts is set to true, and the encoding is set to utf8.

luainputenc is already handled. What is missing for luatex is to set
use_non_tex_fonts to true and the encoding to utf8 if luainputenc is not
used. Unfortunately this is not so easy as with xetex.
