<AWT Dev> RFR: 8027912: [macosx] Provide means to force the headful mode on OS X when running via ssh

[Anthony Petrov]

It's funny how TRUETRUE does the trick :)

Anyway, the fix looks fine to me. Thanks for resolving this issue.

Sergey, and/or Artem, could you please review it, too? We need this fix 
in JDK 8.


PS. I'll push this fix if David doesn't have commit rights to the awt-gate.
