net: ipv6: Set protocol to kernel for local routes

IPv6 stack does not set the protocol for local routes, so those routes show
up with proto "none":
    $ ip -6 ro ls table local
    local ::1 dev lo proto none metric 0  pref medium
    local 2100:3:: dev lo proto none metric 0  pref medium
    local 2100:3::4 dev lo proto none metric 0  pref medium
    local fe80:: dev lo proto none metric 0  pref medium
    ...

Set rt6i_protocol to RTPROT_KERNEL for consistency with IPv4. Now routes
show up with proto "kernel":
    $ ip -6 ro ls table local
    local ::1 dev lo proto kernel metric 0  pref medium
    local 2100:3:: dev lo proto kernel metric 0  pref medium
    local 2100:3::4 dev lo proto kernel metric 0  pref medium
    local fe80:: dev lo proto kernel metric 0  pref medium
    ...
