deps: align vendored drive/ocaml-signal SHAs with the opam pins

CI vendors the lockfile SHAs (opam monorepo pull fills duniverse
before the pin-depends clone loop, which then skips existing dirs).
The lockfile still pointed at drive 7f407b0, which predates the
detach-subtree patch op, so every drive test died in
Drive.Model.apply_op with a non-exhaustive match (26 failures).
ocaml-signal had drifted the same way (868c145 -> df355e1).
