ip_tunnel: Provide tunnel metadata API for CONFIG_INET=n

Browse Source 
Account for the configuration FIB_RULES=y && INET=n as FIB_RULES can
be selected by IPV6 or DECNET without INET.

Fixes: e7030878fc ("fib: Add fib rule match on tunnel id")
Fixes: 3093fbe7ff ("route: Per route IP tunnel metadata via lightweight tunnel")
