selftests/bpf: Test libbpf's ringbuf size fix up logic
Make sure we always excercise libbpf's ringbuf map size adjustment logic
by specifying non-zero size that's definitely not a page size multiple.

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.
