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.
