Anton Protopopov 515ee52b22 bpf: make preloaded map iterators to display map elements count 
Add another column to the /sys/fs/bpf/maps.debug iterator to display
cur_entries, the current number of entries in the map as is returned
by the bpf_map_sum_elem_count kfunc. Also fix formatting.

Example:

    # cat /sys/fs/bpf/maps.debug
      id name             max_entries  cur_entries
       2 iterator.rodata            1            0
     125 cilium_auth_map       524288          666
     126 cilium_runtime_          256            0
     127 cilium_signals            32            0
     128 cilium_node_map        16384         1344
     129 cilium_events             32            0
     ...

WARNING:
If you change "iterators.bpf.c" do "make -j" in this directory to
rebuild "iterators.lskel-little-endian.h". Then, on a big-endian
machine, do "make -j big" in this directory to rebuild
"iterators.lskel-big-endian.h". Commit both resulting headers.
Make sure to have clang 10 installed.
