Subject: Remove unused public zlib include from libapt fileutl.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Our public interface doesn't use zlib for quite a while now so lets drop
the last remnants as hopefully nobody depends on us bringing it in…
Unlike our own private lib for transitive provision of unistd.h.
