libzim changed ABI without a package rename (#1139335).

There are no code changes compared to the libzim that
has been in unstable for 2 months.

The autogenerated tracker looks good.

Control: tags -1 confirmed

Please go ahead.

Hi,
Thank you for taking care of libzim & co. in my absence, I really
appreciate it.

I believe everything has been rebuilt and this can be closed now? If
something still needs to be done I can try to take care of it.

Yes, let's close it.

Cheers,
Emilio
