PR libfortran/35293
* io/unix.c (fd_truncate): Fold s->special_file case into
success case of ftruncate/chsize call instead of the failure case.
Make failure case actually return failure. Properly update stream
pointers on failure. Call runtime_error for targets without
neither ftruncate nor chsize where such a call would be needed.
leads to
