in this patch series i'm adding a helper for libbpf which would allow
it to load map-in-map(BPF_MAP_TYPE_ARRAY_OF_MAPS and
BPF_MAP_TYPE_HASH_OF_MAPS).
first patch contains new helper + explains proposed workflow
second patch contains tests which also could be used as example of usage

v2->v3:
 - fixing typo in patch description
 - initializing inner_map_fd to -1 by default

v1->v2:
 - addressing nits
 - removing const identifier from fd in new helper
 - starting to check return val for bpf_map_update_elem
