RFR: JDK-8240343: JDI stopListening/stoplis001 "FAILED: listening is successfully stopped without starting listening" [v2]

[Alex Menkov]

> The test starts listening on dynamic port and calls stopListening with incorrect (cArgs1) and correct (cArgs2) argument maps.
> Incorrect map is created by finding "free" port (`(new ServerSocket(0)).getLocalPort()`)
> The test fails if the same port is selected later when the listening starts.
> To avoid this free port should be picked after listening on dynamic port started.
> 
> Additionally removed unnecessary `exclusiveAccess.dirs=.` test property and incorrect comment in the description.
> The test uses `SocketListen` connectors, the coment is about `SharedMemoryListen` connector.
> 
> Testing: run the test on all Oracle-supported platforms 100 times
