[libvirt PATCH 02/14] tests: mock libdbus in networkxml2firewalltest

[Pavel Hrdina <phrdina@xxxxxxxxxx>]

This test calls into src/util/virfirewalld.c where it uses DBus to
figure out if firewalld is registered. Without the mock it luckily
fails and the test works correctly.

To isolate the tests from host environment we should mock the DBus
calls.
