We had many false positive reports of failed JCK tests due to missing environment variables. By default, the JCK suite only whitelists a few variables.

Previously we had to specify those variables manually with "-env:", but this isn't suitable for mach5, as there are some variables that are new for every session, like XAUTHORITY.
So JCK-7322838 introduced javatest.processCommand.inheritEnv system property.

Now we need to update mach5 client headful job files to use JCK_LAUNCHER_OPTIONS=-Djavatest.processCommand.inheritEnv=true
