    CI: Remove the build check for pre-build ramdisks only
    
    In the devstack plugin, we identify RAX hosts and change the settings
    slightly to help ensure CI job passage. This is because the machines are
    fully emulated as opposed to paravirtualized which causes a performance
    impact with our test VMs that we create. Since we can hit issues
    while scheduling on RAX in general, it only makes sense to also
    swap the job out for centos based IPA jobs that some how happen on
    to a RAX node. Since the CI jobs have largely been "de-typed" name
    wise, this should be fine.
