bpftool: Use btf_vlen()/btf_kind()/btf_kflag() helpers consistently

Browse source

The btf_vlen(), btf_kind() and btf_kflag() inline helpers defined in
tools/lib/bpf/btf.h are thin wrappers around the BTF_INFO_VLEN(),
BTF_INFO_KIND() and BTF_INFO_KFLAG() UAPI macros - each one simply
returns the corresponding macro applied to t->info.

bpftool already uses these helpers in most places, but 13 call sites
in btf.c and btf_dumper.c still open-code the raw macros. Use the
helpers consistently, matching the rest of bpftool as well as libbpf.

No functional change.
