CI: upgrade to macos-12, and pin OSX version

Per [1] and the warnings our CI is emitting GitHub is phasing in
"macos-12" as their "macos-latest".

As with [2], let's pin our image to a specific version so that we're
not having it swept from under us, and our upgrade cycle can be more
predictable than whenever GitHub changes their images.
