[Sheepdog] [PATCH v5 04/17] sheep: modify the configures to run farm.

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

Drive farm to work!

add two new lib dependency:
 - libssl
 - zlib

Dongsu Park suggests that we should check crypto lib for SHA1_Init
with newer libssl.

Currently libssl-1.0 and libssl-0.9.8 works with current configuration.

For debian based systems, you can install them by the name
zlib1g-dev and libssl-dev.
