Show git revision and build time on the /about page

Add a build package that reads VCS stamping embedded by go build
(vcs.revision and vcs.time from runtime/debug.ReadBuildInfo). The
about handler passes the revision and build time to the template,
which displays them under a "Build info" heading.

Copy .git into the Docker builder stage so VCS stamping works in
container builds.

Inspired by picoshare commit 3248b5d.
