test if fapolicyd can talk to D-bus daemon
    
    Based on the content of reported SELinux denials, the fapolicyd
    service (after its start) wants to communicate with D-bus daemon,
    but SELinux policy does not allow that action. I believe this
    behaviour is expected and it should be allowed in fapolicyd
    SELinux module.
    
    The automated TC looks for appropriate allow rules and it also
    reproduces the issue.
    
    The TC covers BZ#1874491.
