Again, I try to merge fcitx-sogou in

Deepin re-release and upgrade the fcitx-sogoupinyin. Now we can get the binary library only from the repository.
Mr microcai ask me to split the fcitx wrapper and input-engine up because of the different license of them. He is right. But there is only one binary library and only one copyright file in the archive. So what I can do is to ask deepin developer to deal with the license problem and split them.
