routing_table: Parse v6 routes

Since we ultimately handle all of the routes as strings it is safe to
include v6 routes into the table so that we can later support using
those. This has no effect on observed behavior.

Tested:
    Used a future change to validate that this was parsing the default
    gateway for ipv6 and that old ipv4 parsing still works as expected.
