To really verify the presence of the XML prolog, also in CI.
- move the prolog check from `loadtest` to `checktest`.
(load did a soft error, silently skipping the test instead of failing)
- runtests: enable `-w` functionality permanently for all test targets,
drop the option. It has no measurable performance impact.
- test 798, 1665: add XML prolog.
