Revert "utils: file: Use fstatat and unlinkat"

On may of the platforms we build for (RISC OS, Windows, Amiga OS4,
Amiga OS3, and Atari), this was causing:

- utils/file.c:329 error: 'O_DIRECTORY' undeclared
- utils/file.c:357 error: 'AT_SYMLINK_NOFOLLOW' undeclared

This reverts commit ef00567b029ec007ceab342a2ed1addaa5f63be6.
