storage: util: Pass pool type to virStorageBackendFindGlusterPoolSources

The native gluster pool source list data differs from the data used for
attaching gluster volumes as netfs pools. Currently the only difference
was the format. Since native pools don't use it and later there will be
more differences add a more deterministic way to switch between the
types instead.
