Continuation of #50.

Problem description
Trying to compile a tex file with lualatex, or just generating the lualatex format file, fails with something like

fdsan: attempted to close file descriptor 3, expected to be unowned, actually owned by FILE* 0x79ede74418

on android 11 (reported by @panbroggi).

Steps to reproduce
Run lualatex test.tex on some minimal test.tex file, or run luahbtex -ini -jobname=lualatex -progname=lualatex lualatex.ini (which should generate the format file).

Expected behavior
lualatex format file should be generated (if it does not exist) and then the file should be compiled to a pdf.

Additional information

Installing a debug build of texlive-bin and then running

gdb -ex r --args luahbtex -ini -jobname=lualatex -progname=lualatex lualatex.ini

gives this backtrace:

lualatex's source consists of c-files so should be easier to add the disable fdsan patch compared to for pdflatex
