Zip always try to generate new encryption header depending on execution
time and process id, which is far from being reproducible. This commit
changes the zip srand() seed to a predictable value to generate
reproducible random bytes for the encryption header. This will compromise
the goal of secure archive encryption, but it would not be a big problem
for our purpose.
