Add the build-script row, and re-measure everything together

The first numbers were taken twenty minutes apart, and it showed: the build
script came out *faster* than the raw emacs run it wraps, which cannot be true.
All four rows are now measured back to back in one session.

The new row is the point of the exercise. weblorg alone does not group a blog
index by year, write a tags page, rewrite image URLs, minify CSS or emit a
sitemap — so ~600 lines of Python do those on top of it, and the whole publish
is paid again on every run. 49.0s becomes 50.3s.

orgo does three of those five natively. Minification is a build step either way,
and orgo has no sitemap at all — recorded in the README as a gap rather than
quietly left out of the comparison.

Deployment is excluded from every row: it is an rsync over someone's network,
which measures the network.
