apparmor-{geoclue,ofono,tracker}: Explicitly install auditd

The auditd package is being dropped from the images. The audit log can be retrieved from the system journal, and the auditd daemon currently fails to start on the ostree images.

However, the apparmor-{geoclue,ofono,tracker} testcases use the run-aa-test tool which is not trivial to port away from audit.log, so add an explicit installation step for the auditd package to paper over it.
