testdisplay: only set terminal attributes when in foreground process group
The Piglit test runner for intel-gpu-tools creates a new process group for the test processes, so attempting to set terminal attributes causes the process to receive SIGTTOU and be stopped. Since the test is not run interactively in this case, the issue can be avoided by not setting terminal attributes if the process is not in the foreground process group.
