selftests/mm: khugepaged: group tests in an array

Browse Source 
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.
