Revert "Whitelist chromeos wm segfaults until we have a long-term fix"

Now that Dan Erat has updated the VM tests to wait for Chrome
to start up completely before shutting it down, chromeos-wm
should not segfault anymore. So we can remove it from the
whitelist.

See http://gerrit.chromium.org/gerrit/5797 for Dan's CL
to fix the VM tests.

This reverts commit 17faa72c1c329b7bdd5af90218f1e1288328e694
