net: add linux.bootarg parameter from ifup call
This sets a `ip=dhcp` or
`ip=<clientip>:<serverip>:<gatewayip>:<netmaskip>::<iface>:` bootarg for
the network device upon execution of 'ifup'. This is the only point
where we can distinguish between a static ip and a dhcp-based network
setup and thus set a valid bootarg options as it will be required for
nfs boot, for example.
