arptables: Check the mandatory ar_pln match

This match is added by nft_arp_add() to every rule with same value, so
when parsing just check it is as expected and otherwise ignore it. This
allows to treat matches on all other offsets/lengths as error.

Fixes: 84909d171585d ("xtables: bootstrap ARP compatibility layer for nftables")
