libarchive: fix CVE-2013-0211 

CVE description:
Integer signedness error in the archive_write_zip_data function in
archive_write_set_format_zip.c in libarchive 3.1.2 and earlier, when running
on 64-bit machines, allows context-dependent attackers to cause a denial of
service (crash) via unspecified vectors, which triggers an improper conversion
between unsigned and signed types, leading to a buffer overflow.
