Upgrade bazel to 3.4.1 (#1120)

https://github.com/uber/fusionjs/pull/1120

bazel 3.4.0 is basically broken in docker containers: bazelbuild/bazel#11756

After this lands, I will cut a jazelle release that uses bazel 3.4.1, and upgrade fusion CI to use that new jazelle release. I am hopeful that this will fix our bazel server startup issues.
