build-system: update libzip to 1.5.1

This also switches us to libzip's new official home on GitHub, and takes into
account that libzip no longer supports autotools and instead now is cmake
based.

Building against that, on my Mac build system, Subsurface once again correctly
opens DLD files downloaded from divelogs.de.

Fixes #1534
