Test metadata collection in Bors CI workflow

This PR adds a new check to bors CI workflows, which ensures that the metadata collection success, when it's run as part of the `deploy` script. I've only added it to bors workflows, as the runtime will be high while it'll also succeed most of the time. This is a preparation for rust-lang/rust-clippy#8947.
