cannot do make after this pr.
by the way, this is ugly way to fix "libnetwork's logrus version is different from pouchd"
best solution is fork logrus with specific version to such as "alibaba/libnetwork-logrus" then use alibaba/libnetwork-logrus when it is needed by libnetwork.

Thanks a lot for you advice. @u2takey
Please take a look at this to see whether this is reasonable. @rudyfly

@rudyfly @allencloud may be not easy, because import path not match with actual git path.
Can we just upgrade libnetwork, which seems fixed this https://github.com/docker/libnetwork/pull/1856/files.
Or fix makefile so that users can build pouch smoothly.
