Resctrl selftests use very similar functions to cleanup after themselves. This creates a lot of code duplication. Also not being hooked to the test framework means that ctrl-c handler isn't aware of what test is currently running and executes all cleanups even though only one is needed.
Add a function pointer to the resctrl_test struct and attach to it cleanup functions from individual tests.
