Let demo scripts declare their dependencies

Demo scripts should declare their build-time dependencies, to make
them more user-friendly. If a dependency is not met, users should see
an explicit message rather than an incomprehensible error.

Don't rely on the dependencies of individual programs because some
demo scripts use multiple programs and because some scripts might have
additional requirements.
