build: add option to use preinit IP as LAN IP 

We currently have build options to customize the IP address used in the
preinit phase of the boot process, but not to set the default LAN IP.

Introduce a boolean build option that, when enabled, results in the IP
address configured for the preinit phase, to be also used as the default
LAN IP address.
