meta-digi-del: Generate interfaces file on the fly and add ifup.

The interfaces file is different depending on whether we have single
or dual wired ethernet and whether we have a wireless or non wireless
module.

Also, add an ifup script to set the mac addresses fetched from the
kernel command line.

This commit autogenerates the /etc/network/interfaces file.
