openqa: do createhdds on x86_64 workers for now

1539330 is turning out to be pretty intransigent and the images
are getting very old, plus we need f28 branched base images. So
let's do image builds on the x86_64 workers for now. Also re-
enable image builds on workers - I never should've turned that
off in the first place, as they shouldn't be susceptible to the
bug.
