Move to using the environment variables 'ethaddr', 'eth1addr', etc.. instead of bd->bi_enetaddr, bi_enet1addr, etc.

This makes the code a bit more flexible to the number of ethernet interfaces.

Just iterate over eth*addr until we dont find one. I think this isn't as robust os iterating of the aliases, but oh well.
