Add a horrible little hack to get symlink001.py to pass again
This really doesn't give us any regressions in behavior, so it is safe to do although quite ugly. Tell the conflict checking code to ignore symlinks to dirs so that they are not seen as conflicts. Hopefully this entire commit will get factored out soon enough. Signed-off-by: Dan McGee <dan@archlinux.org>
