nftables uses nfnl_[un]lock() and thus depends on CONFIG_NETFILTER_NETLINK.
It's not possible to have nftables built-in when CONFIG_NETFILTER_NETLINK is set
to m.

I also add a dependancy between NETFILTER_XTABLES and NFT_COMPAT instead of
automatically set NETFILTER_XTABLES when NFT_COMPAT is set. This is to avoid a
circular dependency:

net/netfilter/Kconfig:432:error: recursive dependency detected!
net/netfilter/Kconfig:432:	symbol NF_TABLES depends on NETFILTER_NETLINK
net/netfilter/Kconfig:4:	symbol NETFILTER_NETLINK is selected by NETFILTER_NETLINK_ACCT
net/netfilter/Kconfig:7:	symbol NETFILTER_NETLINK_ACCT is selected by NETFILTER_XT_MATCH_NFACCT
net/netfilter/Kconfig:1087:	symbol NETFILTER_XT_MATCH_NFACCT depends on NETFILTER_XTABLES
net/netfilter/Kconfig:425:	symbol NETFILTER_XTABLES is selected by NFT_COMPAT
net/netfilter/Kconfig:478:	symbol NFT_COMPAT depends on NF_TABLES

Applied, thanks Nicolas.
