Does not work with `--output-directory` with either `contour gnuplot` or `contour lua`.

Compile with

broken with the following error:

Compile with:
lualatex --shell-escape test-pgfplots.tex
works.
It seems to be working with more low-level TikZ plots. I.e., the following works:
\begin{tikzpicture}
\draw (-1.5,0) -- (1.5,0);
\draw (0,-1.5) -- (0,1.5);
\end{tikzpicture}
This can be worked aroun, sort of, by setting:
\usepackage{pgfplots}
\pgfplotsset{width=7cm,compat=1.18}
\usepgfplotslibrary{external}
\tikzexternalize[prefix=auctex-aux/]
But this is very-very slow, and requires a hardcoded prefix=<...> in the file.
Works find here, with latest TeX Live 2023 and gnuplot 5.4.8.
line 0: warning: iconv failed to convert degree sign line 0: Cannot load input from 'test-pgfplots_contourtmp0.script'
These were thrown by gnuplot, thus not the fault of LaTeX, including pgfplots package. I find a similar ticket in gnuplot's bug tracker (https://sourceforge.net/p/gnuplot/bugs/2193/), which was solved by setting a utf8 locale.
What is the actual version of lualatex? I can reproduce this reliably without gnuplot:

The same as yours,

With contour lua I can reproduce the problem. Doubt if these two have the same cause.
This fixes the case using contour lua with --output-directory for me (relevent code was introduced in 7f99e13):

\ifpgfplotsplothandlercontour@corners@lockywolf Can you reproduce the original problem (using contour gnuplot and --output-directory) with simpler gnuplot plot, like the first example in pgfmanual (v3.1.10), sec.
22.6 "Plotting a Function Using Gnuplot" (https://tikz.dev/tikz-plots#sec-22.6)?

Your patch does not affect my setup, seemingly.

I know why I can't reproduce it before: there existed *.table from previous run without --output-directory in current working directory.
It seems the call to gnuplot doesn't take value of --output-directory into consideration, see this question posted in 2013 https://tex.stackexchange.com/q/109331.
I suspect that the lua issue is the same issue then. The SO question seems to give a working solution to this issue, given that the value of --output-directory is available in runtime. Could it be added to the pgfplots code somewhere?
