tests: Follow virnetserver to virnetdaemon transition

In a4746114 the virnetserver test was renamed to virnetdaemon.
Moreover, as the test relies on some data stored under
virnetserverdata/ the folder was renamed too. But this was not
reflected in the Makefile. Therefore when building outside of the
repository, the data folder was not distributed and test failed.
