fileops: Allow differentiation between deep and shallow exists()

When calling gitfo_exists() on a symbolic link, sometimes we need to
simply check whether the link exists and sometimes we need to check
whether the file pointed to by the symlink exists.

Introduce a new function gitfo_shallow_exists that only checks if the
link exists and revert gitfo_exists to the original functionality of
checking whether the file pointed to by the link exists.
