Add a handler for show_fdinfo() to be used by the anon-inodes

Does it make sense to include bpf_htab->count in case of a hashmap?
It would give a sort-of only volatile view, e.g. like the map's
refcount. It would be possible to show it, but only as kind of
informative to an admin, have no strong opinion on it, though.
I think this goes rather into the direction of better debugging
interfaces for eBPF, probably makes sense think about it wrt a
general debugging/introspection framework and better dump it
there ...
