[ipv4] Accept unicast packets for the local network broadcast address
The ISC Kea DHCP server transmits its DHCPOFFER as a unicast packet
with a broadcast IPv4 destination address (255.255.255.255). This
combination is currently rejected by iPXE.
Fix by explicitly accepting the local network broadcast address
(255.255.255.255) as a valid unicast destination address.
