Scan destiny.pm and packimage.pm for statements sitting after an unconditional
return, which is how the deprecated provisioning paths stayed in the tree after
they stopped running.
Also assert the behavior that has to survive the removal: the deprecated
nodeset states are still rejected, packimage still rejects -o, -p and -a, and a
missing image name is now reported as such rather than as a missing option that
would be rejected anyway.
