Assuming you have a complete TeXLive installation, you really have
just to call `mtxrun` twice as described above to get the
'luatex-plain' format.  Does it fail for you?

It's not really helpful, alas:

```
> PDFTEX="luatex --fmt=luatex-plain" texi2pdf --verbose a.texinfo 
texi2dvi: Processing a.texinfo ...
texi2dvi: Checking TeX \openout in log support...
texi2dvi: /usr/local/bin/texi2dvi: running luatex --fmt=luatex-plain 
--file-line-error </dev/null '\input' ./openout.tex ...

texi2dvi: TeX neither supports -recorder nor outputs \openout lines in its log
