[PATCH] Fix find -printf %Y on systems with fstatat().

[Nick Alcock]

We were dropping back to the fallback stat (which turns into an
fstatat() with O_NOFOLLOW) even when the return from fstatat()
indicated -ENOENT or -ELOOP, which should be preserved unchanged
so that the caller can print 'L' or 'N' accordingly.

* find/util.c (optionl_stat): Do not use the fallback stat
when -ENOENT or -ELOOP are encountered.
