    Add address family to 'ip rule' calls

    Without an address family, 'ip rule' won't work with IPv6
    arguments because it assumes IPv4. This causes the l3-agent
    to throw an error when adding a rule in DVR mode.

    Also changed these functions to be more symmetrical and take the
    same arguments, which required a little tweaking, but it looks
    much cleaner now.
