test if spamd can search the /var/lib/snapd directory
    
    A recently filed BZ report revealed that SELinux prevents the spamd
    processes from searching (syscall = newfstatat) the /var/lib/snapd
    directory when the snapd package is installed. The TC reproduces
    the situation.
    
    Because the spamassassin service logs indicate that the spamd functions
    are not affected by the denied access, I believe that SELinux policy
    should dontaudit the action. The TC looks for appropriate policy rules
    and file context patterns.
    
    The TC covers BZ#2207725.
