Unable to build go function (default cloudevents template) with s2i builder.

[jrangelramos]

The go function bin is not generated for the default go cloudevent template, when builder is s2i.

The below output is observed

func deploy -v -b s2i -p ./goce --build

This is a S2I go-toolset base image:
To use it, install S2I: https://github.com/openshift/source-to-image
Sample invocation:
s2i build -e IMPORT_URL='github.com/cpuguy83/go-md2man' git://github.com/cpuguy83/go-md2man rhel8/go-toolset go-sample-app
You can then run the resulting image via:

Note: Step 8/9 (assemble script execution output) indicates the source code is not built, thus not producing the gobinary (function executable)
This happens from the default go cloudevents template only.

This error can be observed on the new test being added on the #2401, action https://github.com/knative/func/actions/runs/9682013055/job/26714012883?pr=2401
