Add runtime test for rtla-timerlat's -k/--kernel-threads and
-u/--user-threads options using get_workload_pids.sh to check whether
the appropriate threads are being created.
The tests are implemented for both top and hist. Additionally, all tests
related to timerlat threads are moved to a separate section in the test
files. The latter is also done for rtla-osnoise tests.
