When running watchdog-test with 'make run_tests', the watchdog-test will
be terminated by a timeout signal(SIGTERM) due to the test timemout.

And then, a system reboot would happen due to watchdog not stop. see
the dmesg as below:
```
[ 1367.185172] watchdog: watchdog0: watchdog did not stop!
```

Fix it by registering more signals(including SIGTERM) in watchdog-test,
where its signal handler will stop the watchdog.

After that
  # timeout 1 ./watchdog-test
  Watchdog Ticking Away!
  .
  Stopping watchdog ticks...
