Commit 99bae0209631fd3bf37de1a84d8e2ea396d1dddf in incubator-singa's branch

SINGA-409 [Singa 1.2.0] Basic `singa-cpu` import throws error
It is due to the version mismatch of Protobuf.
In SINGA-396, we updated the protobuf version to be >=3.2.0. And the
singa package is built using 3.2.0.
However, 3.6.1 is installed in your OS. In other words, the runtime env
and the building env mismatch.
In this commit, we fix the version for both building and runtime to
3.6.1.
> Upgrade `protobuf` to 3.6.1 to match Tensorflow's

> `singa-cpu==1.1.1` depends on `protobuf==3.2.0`, but `tensorflow==1.10.1`
