Use latex as the program name for kpsewhich

QuLogic · QuLogic · commit 3a11df436b32 · 2022-01-29T00:30:55.000-05:00
If `tex` is not installed, then setting the program name to it will fail
to find the 'program' in the current directory, and then be unable to
find any TeX files.

Setting it to `latex` should be okay, since that's what we're running
to create the `.dvi` in the first place.
