[GTK] run-gtk-tests should use the driver environment for checking th…

…e accessibility bus

https://bugs.webkit.org/show_bug.cgi?id=161149

Reviewed by Carlos Garcia Campos.

Add a new function for waiting for the accesibility bus. It sets
the test environment variables before starting the GLib mainloop.
And restores the previous environment after it has finished.
It also adds a timeout (5 seconds) to abort in case it has not
been able to detect the accesibility bus before the timeout expires.

* Scripts/run-gtk-tests:
(TestRunner):
(TestRunner._wait_for_accessibility_bus):
(TestRunner._wait_for_accessibility_bus.timeout_accessibility_bus):
(TestRunner._start_accessibility_daemons):
(TestRunner._get_tests_from_google_test_suite): Run this command also with the driver test environment.
