JDK-8199700: SA: Enable jhsdb jtreg tests for Mac OS X

[Lindenmaier, Goetz]

Hi Jini,

I had a look at your change. 
It makes tests fail if shouldSAAttach returns false.

Now, these tests say "Errror: cannot attach",
while before they would terminate silently.

It is not an Error if the SA can not attach. 

You can reproduce this by just changing
Platform.shouldSAAttach() to always return false.

I'll run the patch throuqh our nightly tests to 
see whether they pass mac.

Best regards,
  Goetz.
