Optimizations for main build workflow (#2534)

* Don't upload full dir from gomod step, make some steps parallel.

Uploading/downloading the artifact takes longer than setting up deps
in the test and build steps most of the time.

Also remove double run of `go test` which left over from the time when test
compilation was a separate command.

* comments about gomod and go. files
