Wait for the threads to terminate before finishing the test and exiting
as they could be still running when it exits otherwise, resulting in
crashes in this test case, as happened in a recent CI run:

This crash was difficult to reproduce and only became visible in the CI
after the recent changes resulting in running all the tests in parallel
as this starved this test from having enough cores to mask it. To
reproduce it locally "taskset -c 0 ./test MiscThread::ThreadConditions"
had to be used, this allows to reproduce it under TSAN after just a few
iterations while without taskset it passed 100 times out of 100.
