vfs_fruit: disable fd reopening optimisations for the two special macOS streams

I couldn't figure out why the reopen fails a few vfs.fruit tests, so for now
disable the optimisations. It only affects the two special Mac streams, so it's
not *that* bad, but definitely something we would want to improve on in the near
future.
