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.
