selftests/bpf: ringbuf_multi: Test bpf_map__set_inner_map_fd
...
Test map__set_inner_map_fd() interaction with map-in-map
initialization. Use hashmap of maps just to make it different to
existing array of maps.

selftests/bpf: ringbuf_multi: Use runtime page size
...
Set bpf table sizes dynamically according to the runtime page size
value.
Do not switch to ASSERT macros, keep CHECK, for consistency with the
rest of the test. Can be a separate cleanup patch.

libbpf: Fix ring_buffer__poll() to return number of consumed samples
...
Fix ring_buffer__poll() to return the number of non-discarded records
consumed, just like its documentation states. It's also consistent with
ring_buffer__consume() return. Fix up selftests with wrong expected results.
