This must only be mapped when use_x11==1

Earlier try jobs which did this failed a module import. Either the Python file
always needs to be present (though it won't be invoked except on Linux) or
run_telemetry_as_googletest.py needs to be made more robust to avoid the xvfb
import on non-Linux platforms.
