Bug#1074591: /etc/cron.monthly/acct uses `last` which has been removed from util-linux

[internet2poi...@aim.com]

acct currently does not have any relationship with the new wtmpdb package, 
though, so the cronjob as shipped will never work and will send an error 
message every month.
acct should have a Depends or at least a Recommends for wtmpdb or the cronjob 
should be removed, IMO.
