BPF cpumask selftests need to be added to bpf/prog_tests/cpumask.c to be
run. However, the test_refcount_null_tracking is missing from the main
test file. Add the missing test name to properly trigger the selftest.

Just find out that the invocation of RUN_TESTS(cpumask_success) will
lead to the double test result output for every program in the
cpumask_success.c. Considering we have test the loading of
test_refcount_null_tracking program through cpumask_success_testcases.
It would be better to remove the __success annotation for
test_refcount_null_tracking and the invocation of
RUN_TESTS(cpumask_success) as well.
