Python 2.7's zipfile implementation wrongly thinks that zip64 is
required for files larger than 2GiB. We can work around this by
adjusting their limit. Note that `zipfile.writestr()` will not work
for strings larger than 2GiB. The Python interpreter sometimes rejects
strings that large (though it isn't clear to me exactly what
circumstances cause this). `zipfile.write()` must be used directly to
work around this.
This mess can be avoided if we port to python3.
The bug (b/19364241) in original commit has been fixed.
