KUDU-3093: another band-aid for this DebugUtilTest.TestSignalStackTrace

A TSAN build yielded a stack trace like:

@           0x444a88  __tsan::ProcessPendingSignals()
@           0x4541c1  __interceptor_pthread_mutex_trylock
@     0x7fbca26124e1  kudu::Mutex::TryAcquire()
@     0x7fbca2612893  kudu::Mutex::Acquire()
@           0x4fe036  kudu::MutexLock::MutexLock()
@           0x504abd  kudu::CountDownLatch::WaitUntil()
@           0x504a5f  kudu::CountDownLatch::WaitFor()
@           0x4f04a9  kudu::(anonymous namespace)::SleeperThread()
...

Rather than find the synchronization primitive frame least likely to be
inlined, let's take a more comprehensive approach and search for multiple
candidate frames, including SleeperThread.

I tested this locally in DEBUG, RELEASE, ASAN, and TSAN modes.
