Checkinstall patch, zlib update

Checkinstall wouldn't compile without patches. 

wget http://http.kali.org/pool/main/c/checkinstall/checkinstall_1.6.2-4.dsc
wget http://http.kali.org/pool/main/c/checkinstall/checkinstall_1.6.2.orig.tar.gz
wget http://http.kali.org/pool/main/c/checkinstall/checkinstall_1.6.2-4.debian.tar.gz
dpkg-source -x checkinstall_1.6.2-4.dsc

Zlib needed a version bump.
