ocamlformat: reformat repository to satisfy lint-fmt

Apply ocamlformat 0.20.1 (the version pinned in .ocamlformat) across the
repository. The tree had drifted from the pinned format, which failed
ocaml-ci's lint-fmt check. Also set 'comment-check = false' in .ocamlformat
so ocamlformat tolerates a few pre-existing misplaced (** ... *) doc comments
(warning 50) in src/dns/{operators,packet}.ml[i] instead of erroring out.
Kept as a single isolated commit, separate from the Mirage-update changes.
No semantic changes (formatting only; verified the tree still builds).
