`make try` ran against a fixed directory on one person's machine. It
failed for anyone else, and where that directory existed it rewrote the
checksum attributes and modification times of real files.
It now writes three small files into a new directory from `mktemp -d`,
runs the same sequence of commands on it, and removes it with an EXIT
trap. All steps run in one shell, so the trap also removes the
directory when a step fails.
`TODO.md`: the `try` sentence leaves Next Step and is recorded under
Completed Steps.

attrsum --version now prints the git tag or short commit. make build
stamps it with -X from git describe, and the Dockerfile takes the VERSION
build argument when given, otherwise git describe --tags --always on the
.git in the build context, failing if .git is present and no version
comes out. A new .dockerignore, the canonical one, keeps .git/config out
of the context, and also this repo's host-built /attrsum. CI checks out
full history so it sees the 1.0.0 tag and stamps what a full clone does.
script/docker is replaced with the canonical copy.
