CentOS/RHEL have strict AIDE configs, but Ubuntu's configuration needs extra configuration. This patch adds lines to the end of Ubuntu's AIDE confgiuration to meet the requirements of RHEL-07-021600, RHEL-07-021610, and RHEL-07-021620. Documentation is included. Implements: blueprint security-rhel7-stig Change-Id: I107fa931f80d6871195027be0ed8db4105e2ddf4
