selftests/bpf: add iterators tests
Add various tests for open-coded iterators. Some of them excercise
various possible coding patterns in C, some go down to low-level
assembly for more control over various conditions, especially invalid
ones.
We also make use of bpf_for(), bpf_for_each(), bpf_repeat() macros in
some of these tests.
