Made the run_layout_tests.py script restart the apache2 server before it starts.

  tmpdir = tempfile.gettempdir()

  # Restart the server

  cmd = os.path.join(os.path.abspath(os.path.dirname(sys.argv[0])), "run_apache2.py") + " restart"

  os.system(cmd);

  # Run the tests in path

  cmd = "adb shell am instrument "

  cmd += "-e class com.android.dumprendertree2.scriptsupport.Starter#startLayoutTests "
