selftests: netfilter: add test case for recent mismatch bug
Without 'nft_set_pipapo: fix incorrect avx2 match of 5th field octet"
this fails:
TEST: reported issues
Add two elements, flush, re-add 1s [ OK ]
net,mac with reload 0s [ OK ]
net,port,proto 3s [ OK ]
avx2 false match 0s [FAIL]
False match for fe80:dead:01fe:0a02:0b03:6007:8009:a001
Other tests do not detect the kernel bug as they only alter parts in
the /64 netmask.
