It turns out that dpkg-maintscript-helper isn't currently able to do
this. The current `rm_conffile` removes unmodified conffiles but renames
modified ones with a `.dpkg-bak` suffix. There's an open feature
request, https://bugs.debian.org/1006655 , requesting an
`rm_conffile_if_unmodified`. I think it'd be appropriate to wait on
that, which would then make this fairly trivial.
