This series makes bpftool able to create outer maps (maps of types
array-of-maps and hash-of-maps). This is done by passing the relevant
inner_map_fd, which we do through a new command-line keyword.
The first two patches also clean up the function related to dumping map
elements.
v3:
- Add a check on errno being ENOENT before skipping outer map entry in
dumps.
v2:
- v1 was wrongly expected to allow bpftool to dump the content of outer
maps (already supported). v2 skipped that patch, and instead replaced it
with a clean-up for the dump_map_elem() function.

tools: bpftool: clean up function to dump map entry
tools: bpftool: keep errors for map-of-map dumps if distinct from
ENOENT
tools: bpftool: add "inner_map" to "bpftool map create" outer maps
