libzip: security bump to version 1.3.0

Fixes the following security issues:

CVE-2017-12858: Double free vulnerability in the _zip_dirent_read function
in zip_dirent.c in libzip allows attackers to have unspecified impact via
unknown vectors.

CVE-2017-14107: The _zip_read_eocd64 function in zip_open.c in libzip before
1.3.0 mishandles EOCD records, which allows remote attackers to cause a
denial of service (memory allocation failure in _zip_cdir_grow in
zip_dirent.c) via a crafted ZIP archive.

https://blogs.gentoo.org/ago/2017/09/01/libzip-memory-allocation-failure-in-_zip_cdir_grow-zip_dirent-c/

libzip-1.3.0 also adds optional bzip2 support, so handle that.

While we're at it, add a hash for the license file.
