In the places we run `go build`, we should use
`go build -i` to save the `.a` files generated
during the build. This ensures the artifacts
are availble for other Go tools (linters, IDEs), and
should also improve build speeds.
This changes the example security analyzer from acmecorp/security
to just infosec, to reinforce that we will have certain analyzers
"out of the box" (infosec, cost, etc.)
