RFR(T): 8248746: Undo jhsdb related exclusiveAccess.dirs changes that were done for JDK-8220295

Hello,

Please review the following trivial change:

Due to some issues with running multiple Attach API tests at the same 
time, it was decided to add them all to exclusiveAccess.dirs. This was 
done under JDK-8220295. However, the jhsdb tests should never have been 
added since they don't use the Attach API. They use SA Attach, which is 
completely unrelated. I've been testing with this change for the past 6 
weeks or so, and haven't seen any issues, nor would I expect any.

thanks,

Chris
