zlib: Rebuild with optimization

zlib has switched to cmake. Currently, bee doesn't set a
CMAKE_BUILD_TYPE by default, so the cmake packages are compiled with
CMAKE_BUILD_TYPE=Debug which means, without optimization. For zlib this
is catastrophic, as some operations run 50% slower.

Rebuild zlib with CMAKE_BUILD_TYPE=Release.
