RFR: 8224775: test/jdk/com/sun/jdi/JdwpListenTest.java failed to attach [v2]

[Alex Menkov]

> The fix also partially fixes JdwpAttachTest failures (JDK-8253940).
> The failures are caused by network configuration changes during test execution ("global" IPv6 addresses disappears from interface).
> To minimize chances of intermittent failures like this java.net tests use only link-local addresses whenever possible.
> The fix does the same for JDI tests (Utils.getAddressesWithSymbolicAndNumericScopes  is used by JdwpListenTest and JdwpAttachTest)
