    d1: define subtarget specifically
    
    Historically it's possible to leave the `SUBTARGETS` undefined and
    automatically fallback to a "generic" subtarget. This however breaks
    various downstream scripts which may have expectations around filenames:
    
    While some targets with an explicit generic subtarget contain `generic`
    in the filenames of artifacts, implicit "subtargets" don't.
    
    Right now this breaks the CI[1], possibly also scripts using the ImageBuilders.
    
    Do to the D1 target what's done to other target, explicitly define the
    "generic" subtarget.
