Add build file for libzip

- Build against latest stable release

- Cross-compilation broke somewhere between 0.9 and 0.10, we could
  recommend
    http://www.sourceware.org/autobook/autobook/autobook_255.html
  to upstream so they fix 'zip.h'.
  Provided quick patch meanwhile.

- Added 'Requires: zlib' in the pkg-config file, we could suggest the
  improvement to upstream

- _UPDATE rule implemented

- Test case included

Coded while hacking GNU FreeDink :)
