Upgrade to Go 1.17, add tools.go (#27)

Upgrade code, actions, and Dockerfile to Go 1.17.

Other changes:
- Introduce `tools.go`, to prevent `go.mod` jitter (#20)
- Upgrade golangci-lint from `1.41.1` to `1.42.0`, add `errname` linter
- Bump base Docker image from `debian:buster-20210621-slim` to
  `20210816`

Fixes #20
