Add kernel headers needed from v3.16baserock/pedroalvarez/ebt_ulog-fix

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 the kernel headers needed to build ebtables to the repository
to avoid this problem, and future problems with changes in the kernel headers.
