RFR: 8304286: java/net/SocketOption/OptionsTest.java failing after JDK-8302659 [v3]

[Daniel Jeliński]

> Please review this change that fixes and reenables OptionsTest on Windows.
> 
> The test is checking that the values retrieved from getOption match the values set by an earlier call to setOption. The `IP_MULTICAST_IF` option was tested with the first network interface for which `supportsMulticast` returned true. JDK-8302659 changed the network interface iteration order and the test started failing.
> 
> The proposed change is to verify if the interface is actually usable for multicasting before using it in set/get test. Test passed on all platforms.
