Fail test-image-openj9 target when java -version fails

[jdmpapin]

Previously, the exit status would come from tee, which succeeded.

Does this repo still need to require commit sign-off for some reason? I suspect that it doesn't, and that the failing check is a holdover

If you have good a reason that the check should be removed, then please capture it in an issue. Until we have agreement to remove the signed-off-by check, please update the commit message.

Do you intend to offer equivalent changes for other jdk versions (11, 17, 19, 20, next)?

[jdmpapin]

Oh, thanks, good catch! I should, yes. When I built various versions on my local machine under strace, I only noticed this java -version execution in Java 8, since there it was the only execution of a Java binary from within build/. I thought that it didn't happen in later versions, but it seems that it does and I just didn't notice it. I can see the rule is still there in Main.gmk, and I just re-ran Java 17 make under strace to see that java -version does run.

There a 'next' extensions repo? I don't see one.

Updated this PR so that the changes are consistent with those for later JDK versions

Added quotes for consistency
