tunnel: add a copy of include/linux/if_tunnel.h

This should fix the following compile error:

route/link/ipip.c:52: error: ‘IFLA_IPTUN_MAX’ undeclared here (not in a function)
route/link/ipip.c:53: error: ‘IFLA_IPTUN_LINK’ undeclared here (not in a function)
route/link/ipip.c:53: error: array index in initializer not of integer type
route/link/ipip.c:53: error: (near initialization for ‘ipip_policy’)
route/link/ipip.c:53: error: field name not in record or union initializer
route/link/ipip.c:53: error: (near initialization for ‘ipip_policy’)
