Change the NotifyClamd path to the new freshclam.conf path

Freshclam now notifies the correct configuration about the database defininiton update.
Before this change the old path `/etc/clamav/clamd.conf` was is inside the `freshclam.conf`.

NotifyClamd

Default: The default is to not notify clamd. See clamd.conf(5)'s option SelfCheck for how clamd(8) handles database updates in this case.
