core: use IFF_LOWER_UP instead of IFF_RUNNING for carrier (lp #332064)

Browse Source 
We really have wanted to use IFF_LOWER_UP since 2.6.17 for carrier
status, since that's tied to netif_carrier_ok()/netif_carrier_on() in
the kernel.  See kernel commit b00055aacdb172c05067612278ba27265fcd05ce
for the introduction of IFF_LOWER_UP.
