Re-vendor dependencies with go mod

This is a result of "go mod vendor".
You'll notice that some versions have changed. This is due to the
transient module dependencies that dep wasn't aware of.

For example:
- Gopkg.lock imported cloud.google.com/go v0.41.0 and
  github.com/fsouza/fake-gcs-server v1.11.6
- github.com/fsouza/fake-gcs-server v1.11.6 has a go.mod file that
  depends on cloud.google.com/go v0.43.3:
  https://github.com/fsouza/fake-gcs-server/blob/v1.11.6/go.mod#L4
- therefore, "go mod vendor" bumped cloud.google.com/go to v.0.43.3

Same transient dependency version bumps got applied to some other
modules.

A few are also removed via "go mod tidy".
