SIGTERM should be considered a clean exit code for daemons (i.e. long-running processes, as a daemon without SIGTERM handler may be shut down without issues via SIGTERM still) while it should not be considered a clean exit code for commands (i.e. short-running processes). Let's add two different clean checking modes for this, and use the right one at the appropriate places. Fixes: #4275
