Just came across this bug report and noticed I have the same broken symlink on my machine (weekly updated jessie). I use etckeeper and checked its history. The symlink was added when I first installed docker.io 0.9.0+dfsg1-1.
Another machine which only had docker.io installed on it recently (1.2.0~dfsg1-1) does not have the broken symlink.
