[content shell] add support for invoking testRunner.notifyDone in a different process

Some layout tests, e.g.
http/tests/navigation/no-referrer-target-blank.html create a new
process, and notifyDone() will be invoked in that new process. Add
support for forwarding that signal to the main test runner.

BUG=111316
R=mkwst@chromium.org
TEST=http/tests/navigation/no-referrer-target-blank.html does not time out
