[gnome-builder/wip/chergert/headerbar] omnibar: allow attaching a build result

[Christian Hergert <chergert src gnome org>]

commit 8eb11e4cbf76b819ccd2c7d8b5637c8c201f06d5
Author: Christian Hergert <chergert redhat com>

    omnibar: allow attaching a build result
    
    The omnibar will allow us to see build status and cancel an active build.
    We could certainly use a cleaner abstraction here, but this at least gets
    things wired up.
