    ZOOKEEPER-2664: ClientPortBindTest#testBindByAddress may fail due to "No 
such device" exception

    The following stack trace was observed intermittently:
    ```
    Stacktrace
    
    java.net.SocketException: No such device
        at java.net.NetworkInterface.isLoopback0(Native Method)
        at java.net.NetworkInterface.isLoopback(NetworkInterface.java:390)
        at 
org.apache.zookeeper.test.ClientPortBindTest.testBindByAddress(ClientPortBindTest.java:61)
        at 
org.apache.zookeeper.JUnit4ZKTestRunner$LoggedInvokeMethod.evaluate(JUnit4ZKTestRunner.java:52)
    Standard Output
    ```
    Proposed fix is to catch exception from isLoopback() call and skip the test 
in that case.
