Previously, we built a second copy of libnm-glib that was hacked to use the session bus rather than the system bus, for use by the test programs. Rather than doing that, just have test-nm-client explicitly override the choice of bus. (test-remote-settings-client was actually already doing this, although it leaked the bus after.)
