8059309: network tests fail with "java.net.SocketException: Couldn't obtain phys addr" when run as "root"
Summary: The solaris specific code is changed to use the fallback mechanism if the DLPI interface returns an error indicating that the operation is unsupported. In addition, NetworkInterface::getHardwareAddress is changed to always return null for the loopback interface.
