As it was pointed out by Yonghong Song [1], in the bpf selftests the use
of the ASSERT_* series of macros is preferred over the CHECK macro.
This patch replaces all CHECK calls in bpf_iter with the appropriate
ASSERT_* macros.

After converting CHECK to ASSERT_*, 'static int duration' is not needed any more. Otherwise,
you will hit the following compilation error with latest clang:
/home/yhs/work/bpf-next/tools/testing/selftests/bpf/prog_tests/bpf_iter.c:37:12: error: unused variable 'duration' [-Werror,-Wunused-variable]
37 | static int duration;

1 error generated.
Please remove 'static int duration'.
