…d IDs When CDC ACM is used as stdio the first thread in the test may have a different ID than RIOT-OS#3. The test code will now look at the printed thread information (id, prio) as they are created. This avoids the need for a table with ID/prio.

Contribution description
When CDC ACM is used as stdio the first thread in the test may have a
different ID than #3. The test code will now look at the printed thread
information (id, prio) as they are created. This avoids the need for a
table with ID/prio.
Testing procedure
Run
tests/rmutex_cppwithcompile_and_test_for_board. Choose a board which uses CDC ACM as stdio. That means there are three threads active when the test starts. The test should succeed.Run
tests/rmutex_cppwithcompile_and_test_for_board. Choose a board which uses standard UART for stdio (no CDC ACM). That means there are two threads active when the test starts. The test should succeed.
