script/lint now builds only the lint stage of the Dockerfile, without
the build cache, so every run executes the linter; the image is tagged
simplelog-lint. The lint stage calls golangci-lint directly, since make
lint is itself a docker build of that stage. script/cibuild and
script/docker also build without the cache, so their check steps always
run. script/fmt no longer runs golangci-lint --fix, and script/bootstrap
no longer installs it. golangci-lint config verify is left out, on the
owner's ruling. The README, TODO.md and the script/cibuild comment say
what now runs.
