Subject: [PATCH v2 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.

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.
