selftests/watchdog-test: Fix system accidentally reset after watchdog-test
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...
