    selftests/watchdog-test: Fix system accidentally reset after watchdog-test
    
    [ Upstream commit dc1308bee1ed03b4d698d77c8bd670d399dcd04d ]
    
    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...
