kselftest/filelock: report each test in oftlocks separately

Browse Source 
The filelock test checks four different things but only reports an overall
status, convert to use ksft_test_result() for these individual tests. 
Each test depends on the previous ones so we still bail out if any of them
fail but we get a bit more information from UIs parsing the results.
