- `primitive` is updated to upstream's HEAD which is essentially
   `primitive-0.5.1.0`, plus a core-lint-error workaround for #8355 and
   some minor cleanups.

 - `vector` is updated to upstreams `vector-0.10.9.1` release

Note: The upstream repo location has changed to GitHub,
      hence the update in the `packages` file
