selftests/mm: khugepaged: group tests in an array
Currently khugepaged decides if a test can run using TEST() macro that checks what mem_ops and collapse_context are set by the command line arguments. For better compatibility with ksefltest framework, add an array of 'struct test_case's and redefine TEST() macro to conditionally add enabled tests to that array. Then execute the enabled test by looping the test_case's array.
