zlib: Be more cautious about extracting files using symlinks.
There doesn't seem to be good reason to allow extracting archives with
paths like x/y/z where x or x/y is a symlink: if the symlink points
into the archive, x/y/z could have been resolved at archiving time, and
if x/y/z points outside the archive, we think it's too unsafe to
extract.
