[NETFILTER]: Add CONFIG_NETFILTER_ADVANCED option
The NETFILTER_ADVANCED option hides lots of the rather obscure netfilter
options when disabled and provides defaults (M) that should allow to
run a distribution firewall without further thinking.
Defaults to 'y' to avoid breaking current configurations.
