Raise go.mod version of build/make/tools/rbcrun

Raising the go.mod version to 1.17 or higher enables module graph
pruning (https://go.dev/ref/mod#graph-pruning), which prevents the
go tools like "go build ./..." from loading unused transitive
dependencies, including ones that are missing from our tree.
