This is a problem with python2.7 as well. A change in struct between python2.6

I attempted to re-allow overflow in the struct(...) call by replacing
`zinfo.file_size` with `ZIP64_LIMIT % zinfo.file_size` in zipfile.py, and

can zip big file and these zip file can be open by zipfile.py
it's easy to reproduice
