libxtables: xlate: init buffer to zero
Doesn't affect iptables-xlate, but nft (when built w. xtables support). Without this, nft can print random content if an extension doesn't add anything to the output xlate buffer, e.g. -p mh -m mh can cause nft to print random data after "meta l4proto mobility", as mh ->xlate doesn't do anything in this case.
