netfilter: don't pull include/linux/netfilter.h from netns headers
This pulls the full hook netfilter definitions from all those that include
net_namespace.h.
Instead let's just include the bare minimum required in the new
linux/netfilter_defs.h file, and use it from the netfilter netns header files.
I also needed to include in.h and in6.h from linux/netfilter.h otherwise we hit
this compilation error:
In file included from include/linux/netfilter_defs.h:4:0,
from include/net/netns/netfilter.h:4,
from include/net/net_namespace.h:22,
from include/linux/netdevice.h:43,
from net/netfilter/nfnetlink_queue_core.c:23:
include/uapi/linux/netfilter.h:76:17: error: field ‘in’ has incomplete type struct in_addr in;
And also explicit include linux/netfilter.h in several spots.
