Disable timeout for full_stack_target runs in CI

It seems we've recently been seeing sporadic long-running
full_stack_target cases when running honggfuzz in CI. These
shouldn't be killed (as its possible they hit an error or a deadlock,
especially since the longest-running tests probably have the most
coverage).
