[gnome-builder] omnibar: allow attaching a build result

[Christian Hergert <chergert src gnome org>]

commit 04644fc1617cc2360c1f7faa493589d8913b786a

    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.
