[BlackBerry] Update DumpRenderTree to have it work interactively in parallel

1. Test name is sent to torch-launcher via PPS message(from host machine).
   So we get test list by monitoring and receiving PPS message instead of
   reading file index.drt.
2. Torch-launcher create a <test file>.done file when it finished a test.
3. We don't need to search for Ref-tests in DumpRenderTree.cpp any more. NRWT
   will get them for us.
