RFR: 8292016: Rework JLI_ReportErrorMessageSys [v4]

[Julian Waters]

> Second attempt at resolving [JDK-8292016](https://bugs.openjdk.org/browse/JDK-8292016) with a less intrusive approach this time 
> 
> Side note: While it might be preferred to remove this entirely, other areas of the JDK also use the same flawed logic, and removing this would simply push the issue elsewhere. Fixing this might result in a solution which can be used in those areas in the future.
