meta: firewall: Fix firewalld test with non-abstract sockets

On a recent Fedora Rawhide, dbus-daemon-1.14.8-1 prints a string
prefixed by 'unix:path' instead of the expected 'unix:abstract', thereby
failing the test. Allowing this alternate prefix fixes the test, so for
communication with the daemon it is not relevant.
