Ubuntu 20.04 - reload not supported for unit auditd.service

[NelsonTang19]

The following error when updating the auditd_conf_file resource:

Recipe: auditd::default
  * service[auditd] action reload INFO: Processing service[auditd] action reload (auditd::default line 27)

This seems like a more generic issue of #55
The version of auditd installed on Ubuntu 20.04 is now 1:2.8.5-2ubuntu6 (whereas the version that would be installed in Ubuntu 18.04 is 1:2.8.2-1ubuntu1.1). Running reload with systemd generates the same error:

/usr/bin/systemctl reload auditd
Failed to reload auditd.service: Job type reload is not applicable for unit auditd.service.

A similar fix looks promising:

/usr/sbin/service auditd reload
