    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.
