labs: reduce acct archiving retention
In our standard packages we install 'acct' which does user and process
accounting (see commands 'ac' and 'lastcomm'). The log are held in
/var/log/account which, on labs is a 2GB partition that ends up filling
quite rapidly on busy instances.
On the beta cluster deployment-bastion instance, it takes up to 500MB or
a quarter of the /var instance. Reading the SAL I noticed we keep
cleaning up manually to reclaim disk space.
The files are rotated via a daily cron using the 'savelog' command. It
is passed $ACCT_LOGGING which default to 30 days. Reduce it on all labs
instance to 12 days. On deployment-bastion that would save up roughly
360MB.
Bug: 69604
