Subject: [PATCH v5 0/3] selftests/resctrl: Simplify test cleanup functions

Cleaning up after tests is implemented separately for individual tests
and called at the end of each test execution. Since these functions are
very similar and a more generalized test framework was introduced a
function pointer in the resctrl_test struct can be used to reduce the
amount of function calls.

These functions are also all called in the ctrl-c handler because the
handler isn't aware which test is currently running. Since the handler
is implemented with a sigaction no function parameters can be passed
there but information about what test is currently running can be passed
with a global variable.

Series applies cleanly on top of kselftests/next.

Changelog v5:
- Rebase onto kselftests/next.
- Add Reinette's reviewed-by tag.

Changelog v4:
- Check current_test pointer and reset it in signal unregistering.
- Move cleanup call to test_cleanup function.

Changelog v3:
- Make current_test static.
- Add callback NULL check to the ctrl-c handler.

Changelog v2:
- Make current_test a const pointer limited in scope to resctrl_val
  file.
- Remove tests_cleanup from resctrl.h.
- Cleanup 'goto out' path and labels in individual test functions.
