    fibs_test: Mark same_ip_multiple_ifaces_fib0 as expected to fail
    
    The test relies on being able to assign the same interface address to
    two different tap interfaces; it then removes one of the addresses,
    which at one point would trigger a kernel panic.
    
    Since 361a8395f0b0 it is not possible to assign an address multiple
    times this way, so the test fails.  Just mark it as expected to fail for
    now: if the kernel's behaviour here changes again, this test might be a
    useful seatbelt.
