Fix get_default_host_ip ipv6 address parsing

Browse Source 
This is another occurrence of the issue fixed in bug
1786259 with change I30bf655f which occurs when there
are multiple IPv6 gateways present.

Before this change:
$ source openrc
+++++functions-common:get_default_host_ip:776  ip -f inet6 addr show 100
Device "100" does not exist.

This is because the ip route command returns:
default proto ra metric 100 expires 1497sec pref medium
	nexthop via fe80::4e16:fc01:298c:98ed dev ens3 weight 1
	nexthop via fe80::4e16:fc01:2983:88aa dev ens3 weight 1
