LOG: [lldb/test] Add yield to spin loop in thread_filter test (#191025)

This should fix:
https://lab.llvm.org/buildbot/#/builders/211/builds/7439

The timeout might be caused by three threads busy-spinning at 100% CPU,
starving the CI machine.

Add std::this_thread::yield() to the spin loop to reduce CPU pressure
while keeping threads alive at a debugger-friendly location.
