dahdi.init: Define a default span configuration for digital cards.

If there is a digital card in the system, and there is not a span
configuration line in /etc/dahdi/system.conf, the init script will now create
a temporary default one to use.  On some installations, this will allow
asterisk to start before dahdi is fully configured.

This a temporary measure until DAHDI is always able to provide a timing
source.
