    if_ovpn tests: fix ra test
    
    Client one is supposed to be assigend 198.51.100.2, but sometimes it
    loses the race and the address ends up assigned to client two. When this
    happened one would try to ping itself, which failed because the loopback
    interface isn't up.
    
    Ideally we'd generate static address assignments, but that would
    complicate the test. Activate loopback interfaces so the test always
    passes, and just try to ping both possible addresses.
