boot-order-test: Better separate target-specific and generic parts
The initial version did just PC. I didn't bother to separate out generic parts, because I don't like to abstract from a single case. Now we have two cases, PC and PowerMac, and I'm about to add more. Time to do it right. To ease review, this commit changes the code in-place, and the next commit reorders it for better readability.
