[PATCH 27/27] defaultenv-2: set bootargs correctly for network boot

[Sascha Hauer]

The defaultenv-2 network boot script uses bootargs-ip which
hardcodes eth0 as network device. To make this work with
other nwetork devices use the "ip_route_get" command to determine
the network device used to reach the server.
