RFR: 8237578: JDK-8214339 (SSLSocketImpl wraps SocketException) appears to not be fully fixed

[Clive Verghese]

This PR aims to revert some more cases where SocketExceptions are improperly being wrapped as SSLException. Some work for this was done in [JDK-8235263](https://bugs.openjdk.java.net/browse/JDK-8235263), but that change did not cover all the cases.

As it was mentioned in JDK-8235263, some applications rely on receiving SocketException to decide if the connection should be retried. An example of this would be Apache HTTP client. This PR should ideally fix https://issues.apache.org/jira/browse/HTTPCLIENT-2032
