test: new test, verify SysV start/stop daemon support

Install start-stop-daemon in test root.  Add S01-service.sh, which uses
start-stop-daemon to start service.sh.  Modify service.sh to respect
signals, and not exit immediately when sleep exits due to SIGTERM.
Remove PID file in signal callback and make sure to exit OK

The test itself is basically a copy of the start-stop-service.sh test.
