xtables: Drop use of IP6T_F_PROTO

Setting this bit in cs->fw6.ipv6.flags was done only for rules parsed
from command line, not for those read from kernel. As a result,
appropriate rules could not be deleted. A simple test case is:

| # ip6tables-nft -A INPUT -p tcp -j ACCEPT
| # ip6tables-nft -D INPUT -p tcp -j ACCEPT
| iptables: Bad rule (does a matching rule exist in that chain?).

Since the flag is not used anywhere in xtables-nft, dropping its use fixes
the bug as well as setting it in both cases.
