protobuf: update protoc to latest version (#4038)

Presently, protoc 3.3.0 (released in 2017) is still being used. This
commit updates the vet.sh script as well as existing generated files to
use protoc 3.14.0 instead.

The only concrete change this brings is updated import paths of
Timestamp and Duration types. However, in practice this is a no-op,
since the types themselves are already aliased to the new import path:

- https://pkg.go.dev/github.com/golang/protobuf@v1.4.3/ptypes/duration#Duration
- https://pkg.go.dev/github.com/golang/protobuf@v1.4.3/ptypes/timestamp#Timestamp
