bpftool: Skip pieces of variables in DATASEC

The kernel accepts a variable in DATASEC that is smaller than its type.
It's a piece of a variable that the compiler split, with the type of
the whole variable. bpftool prints a variable by its type, so it reads
past the piece and, when the piece is the last in the section, past
the buffer with the value of the map:

  $ bpftool map dump pinned /sys/fs/bpf/piece
  ".bss": [{
          "whole": 67305985
      },{
          "piece.0": {
              "a": [134678021,1994496712,32592,32,0,833,0,414764080

Only the first number is in the map. Skip the pieces in
btf_dumper_datasec(), like btf_datasec_show() in the kernel does, and
in show_prog_metadata().
