Fix child reaping on fuzzer termination
This commit contains the following changes:
- Call `waitpid()` on the child and the fork server when terminating the
fuzzer; thus, we do not end up with zombies.
- Rename `fsrv.kill_signal` to `fsrv.child_kill_signal`, since the
documentation states that the signal is used to terminate the *child*.
- Use SIGTERM instead of fsrv.(child)_kill_signal, thus the fork server
can always reap the child.
