Add kernel headers needed from v3.16

Ebtables fails to compile with versions of the linux headers greater
than v3.16 with this error:

  extensions/ebt_ulog.c:17:45: fatal error: linux/netfilter_bridge/ebt_ulog.h: No such file or directory
   #include <linux/netfilter_bridge/ebt_ulog.h>

This patch adds netfilter_bridge headers for every supported
extension, including filter.h and types.h, to avoid this problem and
future problems with changes in the kernel headers.
