bug#73831: dvilualatex binary nowhere to be found

[Justin Veilleux]

Hello. I noticed that the dvilualatex binary isn't in the big texlive
package. Is it contained in some other latex package not present in
texlive? I grepped the guix source code and found a mention of
dvilualatex in the `#:create-formats` arguments of the
`texlive-latex-bin`, so I suppose it must be somewhere. Am I missing
something?

Cheers.
