selftests/bpf: Add test result messages for test_task_storage_map_stress_lookup
Add test result message when test_task_storage_map_stress_lookup()
succeeds or is skipped. The test case can be skipped due to the choose
of preemption model in kernel config, so export skips in test_maps.c and
increase it when needed.
The following is the output of test_maps when the test case succeeds or
is skipped:
test_task_storage_map_stress_lookup:PASS
test_maps: OK, 0 SKIPPED
test_task_storage_map_stress_lookup SKIP (no CONFIG_PREEMPT)
test_maps: OK, 1 SKIPPED
