cmd/coordinator: update Dockerfile to Go 1.17
This updates the coordinator to the latest supported version of Go. The
current version of Go labeled golang:1.17 is 1.17.1.
Use go mod download instead of manually trying to install dependencies
because it's easier to maintain and fast enough for our current needs.
Also, use the correct label syntax.
For golang/go#48329
