libalpm: use an lstat wrapper so we never dereference dir symlinks
Linux lstat follows POSIX standards and dereferences a symlink pointing to a directory if there is a trailing slash. For purposes of libalpm, we don't want this so make a lstat wrapper that suppresses this behavior. Signed-off-by: Dan McGee <dan@archlinux.org>
