Derive the image's version from the .git in the build context (closes #366)
upaas uploads its clone as a tar context, which .dockerignore does not filter, so its builds already carried .git; the unknown default of the VERSION build arg is what stamped them. The image now derives its version itself: ARG VERSION has no default, so make build falls back to script/version, which runs git describe on the copied .git; a VERSION build arg still wins.

.dockerignore sends .git without its config in a directory context and no longer leaves out tracked files, which would mark the tree -dirty. The builder installs git, trusts /build as a safe.directory, and fails when .git is present but the version comes out unknown. A shallow single-branch clone stamps its short commit.
