[PATCH bpf-next] libbpf: Make btf_name_info.needs_size unsigned

[Ilya Leoshkevich <iii@xxxxxxxxxxxxx>]

Clang build of libbpf fails with:

tools/lib/bpf/btf_relocate.c:206:23: error: implicit truncation from 'int' to a one-bit wide bit-field changes value from 1 to -1 [-Werror,-Wsingle-bit-bitfield-constant-conversion]
  206 |                 info[id].needs_size = true;
      |                                     ^ ~~~~

Resolve the issue by making needs_size unsigned.
