fix(cros-kernel/x86_64_defconfig) enable CONFIG_NETFILTER_XT_MATCH_ADDRTYPE=m

Docker uses this to manage the network containers properly.
fix(cros-kernel/x86_64_defconfig) enable some more vlan modules

Enable:
	CONFIG_MACVLAN=m
	CONFIG_MACVTAP=m
	CONFIG_VETH=m

Docker needs VETH, and might use MACVLAN in the future, it can't hurt to
enable them, they take up no running space if not used.
