selftests/bpf: Add selftest for bits iter
Add test cases for the bits iter:
- Positive cases
- Bit mask representing a single word (8-byte unit)
- Bit mask representing data spanning more than one word
- The index of the set bit
- Nagative cases
- bpf_iter_bits_destroy() is required after calling
bpf_iter_bits_new()
- bpf_iter_bits_destroy() can only destroy an initialized iter
- bpf_iter_bits_next() must use an initialized iter
- Bit mask representing zero words
- Bit mask representing fewer words than expected
- Case for ENOMEM
- Case for NULL pointer
