cmd/protoc-gen-go: remove reference to legacy ProtoPackageIsVersion4

A reference to this constant was originally generated to ensure that users
were using a sufficiently new version of the github.com/golnag/protobuf
module to avoid subtle runtime incompatibility issues.
Such a technique is not needed if users were using modules,
which would enforce this constraint based on our go.mod requirements.

When we first released the google.golang.org/protobuf module,
we suggested that we would consider removing it after 6 months.
It has now been 7 months since the release.

Fixes golang/protobuf#1077
