I bet that most implementations read this file via open() or fopen(), right?

Then how about adding to the test an open() and an fopen() function that,
instead of opening /etc/shells, opens a data file in gnulib's tests/
(or gltests/) directory?

You know that a function in the main executable overrides the function
in the libc, at least on ELF platforms. We thus might have to skip
the test on macOS, maybe...
