old-run-webkit-tests modifies the registry to configure a post-mortem debugger to save crash logs. This doesn't work on Windows Vista/7 because you need administrator privileges to modify the registry. But old-run-webkit-tests thinks it successfully modified the registry and thus claims to be saving crash logs.
Actually making crash log saving work is covered by bug 44135. But in the meantime we should make old-run-webkit-tests stop lying.

Double-check that modifying the registry worked
