On systems that lack the O_NOFOLLOW open(2) flag, check in
sudo_edit_open() whether the path to be opened is symlink before
opening it.  This is racey but we detect losing the last post-open
and it is better to fail early if possible.  When editing a link
to a non-existent file, a zero-length file will be left behind but
it is too dangerous to try and remove it after the fact.
Bug #753
