Stamp the git commit into images built from the Dockerfile (closes #236)

.dockerignore left out .git, so `make build` in the image found no git
metadata and stamped `dev`. It now sends .git, and no longer leaves out
tracked files (LICENSE, README.md, ...), which git would see as deleted
and mark the version -dirty. The footer and /health already read the
same version. The startup log line that reports it, the logger's
Identify(), was never called; main now calls it. The README says to
build from a git clone.
