eventlogging: manage /etc/eventlogging.d recursively

Removing the declaration for a consumer, as I did in I8ff5716f2, should result
in the consumer config file getting purged. But it doesn't, because the config
file dirs are not recursively managed. Fix that by having Puppet manage it
recursively. Ditto the Upstart job configs in /etc/init/eventlogging.
