fs-tests: integck: get rid of tests_check_test_file_system
Stop using the shared 'tests_check_test_file_system()' function but instead, use own independed version of this function. This is another step forward the goal to make integck independent of the common shared code. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
