webkitpy: Ignore previously launched pid when system is under stress
https://bugs.webkit.org/show_bug.cgi?id=170741

Unreviewed infrastructure fix.

Drivers are destroyed between failing layout tests, which is not necessary and
prevents the work-around implemented in https://bugs.webkit.org/show_bug.cgi?id=170741.

* Scripts/webkitpy/layout_tests/controllers/layout_test_runner.py:
(Worker._kill_driver): Do not destroy drivers when they are stopped.
* Scripts/webkitpy/port/driver.py:
(Driver.stop): Reset driver values set in initializer.
