webrtc build failed for ios simulator

[Sam Gao]

the error detail is as following:

xiaosi@MacBook-Pro src % gn gen out/ios_sim --args='target_os="ios" target_cpu="x64"' --ide=xcode

ERROR at //webrtc.gni:490:32: Assignment had no effect.

        xctest_module_target = "//base/test:google_test_runner"

                               ^-------------------------------

You set the variable "xctest_module_target" here and it was unused before it went

out of scope.

See //testing/test.gni:442:5: whence it was called.

    target(ios_test_target_type, _test_target) {

    ^-------------------------------------------

See //webrtc.gni:447:3: whence it was called.

  test(target_name) {

  ^------------------

See //BUILD.gn:540:3: whence it was called.

  rtc_test("rtc_unittests") {

  ^--------------------------
