RFR: 8219585: [TESTBUG] sun/management/jmxremote/bootstrap/JMXInterfaceBindingTest.java passes trivially when it shouldn't

[Severin Gehwolf]

Hi!

Bug: https://bugs.openjdk.java.net/browse/JDK-8219585

Could somebody please review this trivial testbug. For a config like
[1] the logic prior JDK-8145982 returned this list for
getAddressesForLocalHost():

[localhost/127.0.0.1, localhost/192.168.1.18, localhost/0:0:0:0:0:0:0:1]

Post JDK-8145982, getAddressesForLocalHost() returns:

[localhost/192.168.1.18]

The fix is trivial. Just adjust the condition for as to when the test
should actually trivially pass:

Testing: Manual testing on local setup. jdk/submit (currently running)
