Subject: [PATCH 15/21] uapi: ebtables: don't include linux/if.h

linux/if.h creates conflicts in userspace with net/if.h

By using it here we force userspace to use linux/if.h while
net/if.h may be needed.

Note that:

include/linux/netfilter_ipv4/ip_tables.h and
include/linux/netfilter_ipv6/ip6_tables.h

don't include linux/if.h and they also refer to IFNAMSIZ, so they are
expecting userspace to include use net/if.h from the client program.
