fix(dracut-functions.sh): ip route parsing

Browse Source 
The code for determining local interface and address works
only for peers that are reachable in a single hop.

This is parsed correctly:
192.168.110.1 dev br0 src 192.168.110.160 uid 0 \    cache

But this isn't:
192.168.1.4 via 192.168.110.1 dev br0 src 192.168.110.160 uid 0 \    cache

Fix it.
