xen version/upgrade handling: Improve an error message
When xen-dir cannot find xen-utils, mention that this might be because
xen-utils-<RUNNING-XEN-VERSION> was already removed.
This is generally helpful, but it does not solve the `missing
xenconsoled' problems because 1. it only changes messages and
2. actually in the init script, the error message is currently
discarded anyway (!)
But, anyway, it is an improvemennt.
