modules: style improvments to binNMU()

* use `dpkg-parsechangelog -S $field` to get info from the changelog, instead of
  sedding it (dep on dpkg-dev >= 1.7.0)
* use log.[ew] instead of plain echo
* use cat > $tmpcl << EOF instead of that list of echo
* use mktemp to create the temporary changelog, instead of fixing on one filename
* add a lot of quotes
