IMPALA-10160: Add test for kernel_stack_watchdog
IMPALA-13844 registered the Kudu stack trace signal handler, which also
fixed IMPALA-10160 where slow RPCs would trigger the KernelStackWatchdog
to print a stack trace, but no stack trace could be generated because
the signal handler was not installed. Adds a test to avoid regressing.

> Kudu 1.7 provides a util to dump the stacktraces of all native threads
> (KUDU-2291) and adds a /stacks page in the WebUI for that purpose. An example
> output:
> https://gist.github.com/toddlipcon/b64739ee5fb146ea1953380f57b996c4
> Impala can adds the same page since the code is also ported:
> https://github.com/apache/impala/blob/6f2ac8a4067558a1eee58eb506275d22049fdba3/be/src/kudu/util/debug-util.h#L253
