rawhide ppc64le/ppc64 iso do not boot after compose 20180517
as per openQA last run:
probably something wrong in the iso build process.
Need to compare compose logs between 20180517 and 20180515.
The "lorax phase" failed after kernel-bootwrapper sub-package removal (at least in 0516), but is fixed in https://github.com/weldr/lorax/pull/362, sounds like there is ISO, but not bootable. Todays (0518) compose should use the fixed lorax and be good in this regard.
Looks to me the ISO creation when lorax fails isn't skipped every time. The netinst ISO is skipped (for both the Everything and Server composes), but "fat" ISO for Server is created, while it should be skipped as well.
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle.
Changing version to '29'.
