Binary package hint: tomcat6

In cases where the tomcat6 group already exists (eg ldap), the postinst fails due to running addgroup blindly.
Commenting out the addgroup works fine, although that isn't a generic fix.

> addgroup --system "$TOMCAT6_GROUP" --quiet
> if ! id $TOMCAT6_USER > /dev/null 2>&1 ; then

(I had a better bug report with more detail, but the "no referrer" error ate it. Lovely..)
