RFR: JDK-8262199: issue in jli args.c [v4]

[Matthias Baesken]

> Sonar reports a finding in args.c, where a file check is done .
> Stat performs a check on file, and later fopen is called on the file .
> 
> The coding could be slightly rewritten so that the potential issue is removed (however I do not think that it is such a big issue).
