[zlib] Update minizip to the latest version

This pulls in the latest version from
https://github.com/madler/zlib/tree/develop/contrib/minizip and applies
(and updates) our .patch files.

One behavior change is that this enables minizip to open empty
zip files (where the End of Central Directory Record occurs at
offset zero).
