    packagefeed-stability.bbclass: copy all packages of a recipe
    
    A recipes can generate several rpms such as a.rpm, a-dev.rpm, a-dbg.rpm,
    when update one of them in the repo, we'd better update all of them,
    otherwise, there might be a-dev.r0.1.rpm and a-dbg.r0.3.rpm in the repo,
    which looks strange.
