I think the right answer is actually a partial revert.  The change to
Debconf::ConfModule was overkill on my part: it isn't necessary to fix
the original bug, and it causes this kind of problem.  I have an
alternative implementation which only affects dpkg-reconfigure, so won't
break ordinary maintainer scripts like this; I'm just testing it a bit
before upload.

That said, using absolute paths (as has been done though not yet
uploaded for #867256, I see) when calling ucf still seems like a good
idea for robustness.
