Skip LaunchInTerminalTestCase test on remote systems

Summary:
This ability was added by @jasonmolenda in [[ http://reviews.llvm.org/rL225748 | r225748 ]] but it was commented out because he hadn't test it.
I tested it on OS X and now we can enable it legally.

This change is made by @chying request.
