Convert test_cgroup_attach to prog_tests. This change does a lot of things but in many cases it's pretty expensive to separate them, so they go in one commit. Nevertheless the logic is ketp as is and changes made are just moving things around, simplifying them (w/o changing the meaning of the tests) and making prog_tests compatible: * split the 3 tests in the file into 3 separate files in prog_tests/; * rename the test functions to test_<file_base_name>; * remove unused includes, constants, variables and functions from every test; * replace `if`-s with or `if (CHECK())` where additional context should be logged and with `if (CHECK_FAIL())` where line number is enough; * switch from `log_err()` to logging via `CHECK()`; * replace `assert`-s with `CHECK_FAIL()` to avoid crashing the whole test_progs if one assertion fails; * replace cgroup_helpers with test__join_cgroup() in cgroup_attach_override only, other tests need more fine-grained control for cgroup creation/deletion so cgroup_helpers are still used there; * simplify cgroup_attach_autodetach by switching to easiest possible program since this test doesn't really need such a complicated program as cgroup_attach_multi does; * remove test_cgroup_attach.c itself.
