All fib_rule users cannot be compiled as module.

  $ grep -E "config (INET|IPV6|IP_MROUTE|IPV6_MROUTE)\b" -A1 \
    net/{Kconfig,{ipv4,ipv6}/Kconfig}
  net/Kconfig:config INET
  net/Kconfig-	bool "TCP/IP networking"
  --
  net/ipv4/Kconfig:config IP_MROUTE
  net/ipv4/Kconfig-	bool "IP: multicast routing"
  --
  net/ipv6/Kconfig:menuconfig IPV6
  net/ipv6/Kconfig-	bool "The IPv6 protocol"
  --
  net/ipv6/Kconfig:config IPV6_MROUTE
  net/ipv6/Kconfig-	bool "IPv6: multicast routing"

Let's remove EXPORT_SYMBOL and friends for fib_rule.
