Revert "Upgrade //third_party/protobuf to v3.2.0"
This reverts commit 2346f5a01561f695a2b2ba7655359d5020105077.
It breaks bazel build in freebsd[1]. The solution is to patch
https://svnweb.freebsd.org/ports/head/devel/protobuf/files/. I
rolled-back this since the other builds will not automatically start if
Bazel is broken.
