If the dhcp server provided an interface-mtu option, transcribe the value
to the boot.netif.mtu env var, which will be picked up by pre-existing code in nfs_mountroot() and used to configure the interface accordingly. This should bring the same functionality when the bootp/dhcp work is done by loader(8) as r297150 does for the in-kernel BOOTP case.
