Add configure check for zlib with inflateInit2
and replace old unused and poorly named FIND_ZIP. The new code prefers pkgconfig and only falls back to manual detection if needed. This also prioritizes detected zlib flags and includes to be preferred over the ones that are added by pkgconfig for libpng, tifflib etc. which would otherwise have caused the system default zlib to be used.
