Subject: [PATCH v5 15/16] selftests/resctrl: Remove mongrp from CMT test

The CMT selftest instantiates a monitor group to read LLC occupancy.
Since the test also creates a control group, it is unnecessary to
create another one for monitoring because control groups already
provide monitoring too.

Remove the unnecessary monitor group from the CMT selftest.
