RFR 8085575_8130657, misc fixes for a few of java.net intermittent failures

[Felix Yang]

Hi there,

    please review following patch to a few of java.net tests.
Bug:

    https://bugs.openjdk.java.net/browse/JDK-8085575

Add retry for java/net/Socket/InheritHandle.java. Though it may be 
unable to resolve all BindException ( I suppose it is the nature of such 
close-reuse scenarios), it will be helpful to avoid failures from 
asynchronized close, which has been observed especially on Windows. Also 
some misc changes on other two tests.


Thanks,

Felix
