dahdi_genconf: Use 'dahdi_scan' to determine span_type for B410P cards.

The wcb4xxp driver does not put enough information in the proc filesystem to
determine if the ports are in TE or NT mode.  Previously the ports would
always just setup the dahdi-channels.conf file in TE mode. After this change
the dahdi_scan utility is used to detect if the ports are in TE or NT mode and
setup dahdi-channels.conf appropriately.
