RFR: JDK-8139951 Do not store debug level in OPT part of Verona string

Tue Oct 20 09:11:00 UTC 2015

After discussion, it was decided that debug level information should not 
be a part of the new version string as implemented in Verona. Instead, 
this information should be propagated using other means. (Follow-up bugs 
will be filed for this).

This bug removes the debug-level from the opt part of the version string.

Note that this fix will be pushed to verona/stage.
